Second source for O-rings and seals
To set up Conquest Seal as a second source for O-rings and seals, send the part number, dash number or drawing from your current order, and a person replies within one business day. Every order ships with a certificate of conformance naming the part number, the specification, the manufacturer, the lot and the quantity, with the manufacturer's cure date on elastomer parts. 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. Conquest buys from the manufacturer or its distribution network and quotes to your print: the O-ring size by its AS568 dash number, and the material to the specification the print names.

What ships with each order
Each document answers a different question at receiving inspection, and the last column says when it ships from Conquest. The certificate of conformance comes with every order; the others follow the part and the program.
| Document | What it states | When it ships |
|---|---|---|
| Certificate of conformance | The parts conform to your order and the specification it names; it names the part number, the specification, the manufacturer, the lot and the quantity, and on elastomer parts the manufacturer's cure date | Every order |
| Packing list | The parts and quantities in the shipment | Every order |
| Manufacturer's certificate of conformance | The manufacturer's own statement that its lot meets the document | With specification parts |
| Batch test report | Measured results for the batch against the specification's tests | Where the program requires it and the manufacturer issues one |
| Compound data sheet | Typical properties of the compound, not of your lot | On request |
| AS9102 first article inspection report | Every drawing characteristic verified on a representative part | On request |
| RoHS, REACH and conflict minerals statements | Declarations for the part numbers or compounds you name | On request |

How a part number crosses to Conquest
An O-ring's size crosses exactly, because the three-digit dash number is the AS568 size whatever prefix a maker puts in front of it. The material crosses to the specification your print names, not to a maker's compound code, which only identifies that maker's own compound. Where the print names one maker's compound and nothing else, an equal is a decision for whoever owns the print, and Conquest quotes the equal your engineering approves, with the maker's sheet. Molded seals, hydraulic seals and gaskets are quoted to the part number or drawing on your order. The part number cross-reference guide works through common callouts, and the mil-spec O-ring index gives the current document behind each military family.
Where the parts come from
Conquest buys from the manufacturer or its distribution network, and the certificate of conformance names the manufacturer, so the lot traces back past Conquest to the company that made it. When your print calls out a specification that has a qualified products list, the material or the finished molded part comes from a listed manufacturer, and the certificates name that manufacturer. Gaskets are cut to your drawing on Conquest's own waterjet. Orders are handled under Conquest Seal's AS9100D quality management system, whose certificate scope includes distribution; the certificate and its scope are on the quality and certifications page.
Counterfeit prevention and records
Conquest works to a written procedure for preventing counterfeit products, covering monitoring, detection and awareness. Its purchase orders bar suppliers from shipping counterfeit or suspect counterfeit goods, and every order to a supplier requires certificates and batch and cure dates, so a lot arrives with its pedigree. Certificates are kept permanently for customers whose contracts require it, and for 15 years otherwise; digital records, kept from 2020 on, are retained indefinitely. The supplier requirements page sets out the clauses, and the compliance documents page lists what a purchasing team asks for at onboarding.

Frequently asked questions
How do I add Conquest Seal as a second source?
Send the part number, dash number or drawing from your current order through the quote form, with the quantity and the documents your program needs. A person replies within one business day, and the quote names the manufacturer and the compound.
What paperwork comes with a Conquest order on an aerospace program?
A certificate of conformance ships with every order, naming the part number, the specification, the manufacturer, the lot and the quantity, with the manufacturer's cure date on elastomer parts. For specification parts the manufacturer's own certificate ships with it, and a batch test report goes with the order where the program requires one and the manufacturer issues it. An AS9102 first article report is available on request.
Can Conquest supply M83248 O-rings with a certificate of conformance?
Yes. M83248/1 and M83248/2 rings are specification parts, so the manufacturer's own certificate ships with Conquest's certificate of conformance. The M83248 page covers both slash sheets and the documents behind them.
Is Conquest on a qualified products list?
No. A listing belongs to the manufacturer's product, not to the distributor that supplies it. When your print calls out a specification that has a list, the material or the finished molded part comes from a listed manufacturer, and the certificates name that manufacturer.
Does Conquest decide whether a substitute is an equal?
No. Whether another maker's compound is an equal on your print is the decision of whoever owns the print. Conquest quotes the equal your engineering approves and sends the maker's sheet with the quote.
Does the same paperwork come with hydraulic seals and gaskets?
Yes. A certificate of conformance ships with every order, whatever the part: O-rings, molded seals, hydraulic seals or gaskets cut on Conquest's own waterjet. On elastomer parts it prints the manufacturer's cure date, and the manufacturer's certificate ships with specification parts.
How long does Conquest keep its certificates?
Certificates are kept permanently for customers whose contracts require it and for 15 years for everyone else. Conquest's digital records, kept from 2020 on, are retained indefinitely. If your contract sets its own retention period, put it on the purchase order.
