Vendor consolidation for O-rings, seals and gaskets
Vendor consolidation with Conquest Seal means buying the O-rings, gaskets and other seals on your part list from one supplier: one supplier to set up, one part list to quote, and a certificate of conformance with every order, whatever the part. We stock every AS568 size and cut gaskets to your drawing on our own waterjet in Orange, California; the other lines come from the manufacturer or its distribution network, and custom molded parts can also be made to your print through our overseas manufacturing program. Parts your line uses order after order can sit on our shelf and ship against a blanket purchase order, or be replenished to a level you agree with us. Send the part list you buy from several suppliers today, and a person replies within one business day.

What one supplier covers
Conquest supplies the product lines below, and one part list can mix them. The last column says how each line reaches you: from our stock, cut on our own waterjet, or from the manufacturer that makes it, named on the quote.
In the two years to September 2026, customers who have bought 50 or more different part numbers from us made up 72 percent of our sales.
| Product line | What is supplied | How it is supplied |
|---|---|---|
| O-rings | Every AS568 inch size, and ISO 3601 metric sizes | Every AS568 size from our stock, in the compounds its size page names; metric sizes and other compounds quoted to your drawing |
| Gaskets | Gaskets cut to your drawing from sheet | Cut on our own waterjet in Orange, California |
| Custom molded rubber | Parts no catalog carries, made to your drawing by compression, transfer or injection molding | From a domestic manufacturer Conquest Seal distributes for, or made to your print through our overseas manufacturing program, with Conquest Seal as the manufacturer of record |
| Mechanical seals | Cartridge and component styles for pumps and other rotating equipment | From the manufacturer or its distribution network |
| Hydraulic seals | Rod seals, piston seals and wipers in inch and metric profiles, quoted to your size | From the manufacturer or its distribution network |
| Radial shaft seals | Single lip, double lip and spring-loaded, sized to the shaft, bore and width | From the manufacturer or its distribution network |
| Rubber-to-metal bonded | Rubber on a metal insert, so one part seals, mounts or damps | Made to your print by the manufacturers we source from |
| Rubber compounds | Standard grades and the AMS and MIL specification grades a drawing can call out | From the compounders and manufacturers we source from |
| Machined plastic parts | Seats, back-up rings and bushings in PTFE, PEEK, UHMW and nylon | Machined to your print by the shops we source from |
Each line has its own page: O-rings, gaskets, custom molded rubber, mechanical seals, hydraulic seals, radial shaft seals, rubber-to-metal bonded parts, rubber compounds and machined plastic parts.
Stocking, releases and vendor-managed inventory
A stocking program starts from your part list: the part number, specification or drawing, compound and usage for each part. We agree with you which parts to hold and at what level, and the program is written for you. AS568 sizes come from our stock, and specification and custom parts are ordered from the manufacturer to the agreed level. Changes to the list, the compound or the revision go through the same written agreement.
Releases run against a blanket purchase order, and each release is numbered on our order, so your open-order report and ours match release by release. Under vendor-managed inventory we hold the agreed items against your usage and replenish them to the agreed level, with the minimum, the maximum and the review cadence written into the program. The levels are reviewed against your actual usage and changed with you, never on our own. Send your open-order report as it comes out of your system, and we check every line against our order book and answer with the differences.
In the two years to September 2026, customers who order against a blanket purchase order made up 27 percent of our sales.
One set of paperwork for every line
A certificate of conformance ships with every order, whatever the part, naming the part number, the specification, the manufacturer, the lot and the quantity, with the manufacturer's cure date on elastomer parts. A packing list ships with every order too. For specification parts the manufacturer's own certificate ships with it, a batch test report goes with the order where the program requires one and the manufacturer issues it, and an AS9102 first article report is available on request. Every lot is received against the purchase order and the specification, with its identity, quantity and paperwork checked, and lot traceability runs from the manufacturer's certificate through our receipt and shipment.
With one supplier, onboarding is one supplier file instead of one per product line. Send your supplier questionnaire or document list with the part numbers you plan to buy, and the documents that depend on the part, such as the RoHS, REACH and conflict minerals statements and the manufacturer's certificate, come back tied to those part numbers. The quality certificate, the counterfeit-parts prevention practice and the record retention periods are on the compliance documents page.
Custom molded parts on the same part list
A custom molded rubber part can go on the same part list as your O-rings and gaskets, and it reaches you one of two ways. On the domestic route, the part is made by a domestic manufacturer Conquest Seal distributes for, and that manufacturer is the manufacturer of record on the certificate. On the import route, the part is made to your print through our overseas manufacturing program and imported, and Conquest Seal is the manufacturer of record and issues the certificate. The quote names the route each part takes.
Either way the order ships with a certificate of conformance, like every order, and the material certification and a batch test report can be requested with the quote. For a molded part, send the drawing, the material callout, the quantity per release and per year, and whether a mold already exists and who holds it. The custom molded rubber page covers both routes and what to send.
Moving parts from your other suppliers
Parts you buy from other suppliers today are quoted to the part number, dash number or drawing on your order. An O-ring's size crosses by its AS568 dash number, whatever prefix a maker puts in front of it, and the material crosses to the specification your print names. Where your print names one maker's compound and nothing else, whether another is an equal is the decision of whoever owns the print, and we quote the equal your engineering approves, with the maker's sheet. The second source page and the part number cross-reference guide cover crossing a part in more detail.
What to send for a quote
- The part list: each part number, AS568 dash number or drawing, with its revision
- The specification and the compound, where the print names them
- The quantity and the usage, and the blanket order or release schedule if you have one
- The documents your program needs beyond the certificate of conformance
- Your supplier questionnaire, if you are setting Conquest up as a new supplier
Send it through the quote form, which takes a PDF part list or a drawing as a file, or by email from the contact page, and a person replies within one business day.
Please don't send a drawing marked ITAR, EAR, CUI or export-controlled. For those parts, call (714) 632-9830.
Frequently asked questions
What does vendor consolidation mean at Conquest Seal?
It means buying the O-rings, gaskets and other seals on your part list from Conquest instead of from several suppliers. You set up one supplier, send one part list for a quote, and receive a certificate of conformance with every order, whatever the part. Parts you use order after order can be held on our shelf under a stocking program.
Which product lines can Conquest supply?
O-rings, gaskets, custom molded rubber, mechanical seals, hydraulic seals, radial shaft seals, rubber-to-metal bonded parts, rubber compounds and machined plastic parts. Gaskets are cut on our own waterjet in Orange, California, and the other lines come from the manufacturer or its distribution network, named on the quote. Custom molded parts can also be made to your print through our overseas manufacturing program, with Conquest Seal as the manufacturer of record.
Do other customers already buy from Conquest this way?
Yes. In the two years to September 2026, customers who have bought 50 or more different part numbers from us made up 72 percent of our sales, and customers who order against a blanket purchase order made up 27 percent of our sales.
Can Conquest hold stock for our production line?
Yes. We stock every AS568 size, and a stocking program holds the parts your line uses at a level agreed with you, with specification and custom parts ordered from the manufacturer to that level. Releases run against a blanket purchase order, or the items are replenished to the agreed level under vendor-managed inventory.
Is the paperwork the same for every product line?
Yes. A certificate of conformance ships with every order, whatever the part, naming the part number, the specification, the manufacturer, the lot and the quantity, with the manufacturer's cure date on elastomer parts. The manufacturer's own certificate ships with specification parts, and an AS9102 first article report is available on request.
How do we reconcile open orders with Conquest?
Send your open-order report as it comes out of your system, with the purchase order, part, quantity and due date. We check every line against our order book and answer with the differences: quantity, date, lines not on our book and lines already shipped. Blanket releases are matched by release number.
Does moving a part to Conquest change who approves it?
No. We quote to the part number or drawing on your order, and whether another maker's compound is an equal on your print is the decision of whoever owns the print. We quote the equal your engineering approves and send the maker's sheet with the quote.
Who replies when we send a part list?
A person reads every quote request and replies within one business day. Any question about a part comes back by email or phone.
