Mil-spec part number, M83461/1 family

M83461/1-114 O-ring: nitrile (NBR), the AS568-114 size

M83461/1-114 is the AS568-114 O-ring size, 0.612 in (15.54 mm) inside diameter by 0.103 in (2.62 mm) cross-section, in nitrile (NBR) procured to MIL-P-83461/1. The DLA ASSIST and SAE Mobilus records read: Canceled (MIL-P-83461/1); AS83461/1C current (revised 2016, reaffirmed 2021). The same part is also printed as AS83461/1-114. The dash sets the size and the document sets the compound, so an AS568-114 in another compound is not the same part as M83461/1-114. Send the designator exactly as the print reads and we quote it against that document.

Same nominal size, other documents

Other part numbers for the AS568-114 size

These part numbers name the AS568-114 nominal size under a different document, so each one is a different compound. They are not interchangeable with M83461/1-114 unless the print or the buyer's engineering allows it. At this size the family sheets for MS28775-114, MS29513-114 and AS9386-114 hold a tighter inside-diameter tolerance than AS568.

The base polymer

M83461/1-114 is nitrile (NBR). The Parker® O-Ring Handbook ORD 5700 range published for the NBR family (section 2.2) is -34 C to 100 C. That is the polymer family's range, not this document's requirement; the compound sheet for the qualified grade governs.

Material page: Nitrile (NBR) O-rings. Every document in the family: M83461/1 O-rings.

Frequently asked

What is the AS568 equivalent of M83461/1-114?

M83461/1-114 is the AS568-114 size: 0.612 in (15.54 mm) inside diameter by 0.103 in (2.62 mm) cross-section. The dash sets the size; MIL-P-83461/1 sets the nitrile (NBR) compound. An AS568-114 ring in any other compound has the same dimensions but is not the same part as M83461/1-114.

What is the NSN for M83461/1-114?

DLA's public FLIS data lists M83461/1-114 on NSN 5331-01-107-4954 (read 2026-10-08). An NSN is the federal catalog's number for the item; your contract or print decides what is ordered.

Is MIL-P-83461/1 still active?

The document status reads: Canceled (MIL-P-83461/1); AS83461/1C current (revised 2016, reaffirmed 2021). It comes from the DLA ASSIST and SAE Mobilus records listed under Sources, with the date each was read. A canceled or inactive MIL document can still be the one a print calls out; the SAE document named in the status is the current one, and your print decides which you order to.

How do I order M83461/1-114?

Send the designator exactly as the print reads, with its revision, any suffix letter, the quantity and the paperwork the order needs. M83461/1-114 is quoted and supplied against MIL-P-83461/1 or SAE AS83461/1, in the compound the print calls out, with a certificate of conformance with every order. When the print calls out a QPL-listed specification, the finished molded O-ring, or the material it is molded from, comes from a manufacturer listed on that QPL; Conquest supplies it and is not itself on any QPL. A Conquest representative replies within one business day.
