Mil-spec O-ring family, nitrile, hydrocarbon fuel
MS29513 O-rings: nitrile for hydrocarbon fuel to AMS-P-5315 and AS29513
MS29513-XXX specifies a nitrile (NBR) O-ring for hydrocarbon fuel with the AS568 nominal size of the same dash, and MS29512-YY the same material in the straight-thread tube-fitting boss sizes; the DoD size sheets hold a tighter inside-diameter tolerance than AS568 above 0.500 in. The governing MIL-P-5315 was cancelled on 2002-02-28 in favor of SAE-AMS-P-5315 (current at revision C of 2022-08-05), and the drawings are current as SAE-AS29513C and SAE-AS29512C, both revised in October 2016 and reaffirmed on 2021-11-09.

Designator to AS568 size
MS29513-XXX and AS29513-XXX carry the three-digit AS568 dash, and MS29512-YY and AS29512-YY the two-digit tube-fitting boss dash, which names the tube outside diameter in sixteenths of an inch and has the AS568-9YY nominal size. The DoD size sheets, MS29513 Revision C and MS29512 Revision C, give each dash the AS568 nominal inside diameter and cross-section of the same dash but hold a tighter inside-diameter tolerance than AS568 above 0.500 in, so the part has the AS568 nominal size, not the AS568 tolerance, and the drawing governs. The MS29513 sheet does not list sizes 102 to 109, 201 to 209 or 309 to 324, so this page gives those callouts no AS568 size; send them as the print reads them.

Where the documents stand
MIL-P-5315 was the hydrocarbon fuel resistant packing document behind both MS drawings. DLA ASSIST records it inactivated on 1997-12-31 and cancelled on 2002-02-28, superseded by SAE-AMS-P-5315, which is current at revision C of 2022-08-05. The drawings, MS29513 Revision C (1966) and MS29512 Revision C (1965), were canceled on 2001-03-01 and moved to SAE as AS29513 (standard sizes) and AS29512 (tube-fitting boss sizes) with the part numbers unchanged; both are current at revision C, revised in October 2016 and reaffirmed on 2021-11-09, and both titles keep the MS number's words hydrocarbon fuel resistant.
A print that reads MS29513 or MS29512 is therefore quoted against AS29513 or AS29512 for the drawing and AMS-P-5315 for the material. The callouts did not change.
The base polymer
The polymer behind this family is nitrile (NBR). The Parker O-Ring Handbook ORD 5700 family range for Buna-N (NBR) (section 2.2, read 2026-09-14) is -34 C to 100 C; that is the polymer family's range, not this document's requirement, and the compound sheet for the qualified grade governs. Parker notes that specification temperature limits do not necessarily represent operating temperature limits.

How we quote this family
Send the designator as printed, MS29513-XXX or MS29512-YY (or the AS29513 / AS29512 form), with the dash, the quantity and the certification the order needs. We quote it supplied against AMS-P-5315 and the AS drawing, in the fuel-resistant nitrile compound the document calls for, with a certificate of conformance and lot traceability. If the print names a compound number, include it and we quote that compound.

Frequently asked
What is an MS29513 O-ring and what durometer is it?
A nitrile (NBR) O-ring for hydrocarbon fuel, made to MIL-P-5315 and now to SAE-AMS-P-5315 with SAE-AS29513 as the drawing. Manufacturers supply it at 70; Parker ORD 5700 (2021) lists its N0602-70 against the document in the 65 to 75 band. Confirm the durometer against your print.
What is the difference between MS29513 and MS29512?
Size series only. MS29513 (now AS29513) carries the standard sizes with the three-digit AS568 dash, and MS29512 (now AS29512) the straight-thread tube-fitting boss sizes with a two-digit dash, the tube outside diameter in sixteenths of an inch, which has the AS568-9YY nominal size. Both DoD sheets hold a tighter inside-diameter tolerance than AS568 above 0.500 in. Both are the same fuel-resistant nitrile under AMS-P-5315.
Is MIL-P-5315 still active?
No. DLA ASSIST lists it cancelled on 2002-02-28 and superseded by SAE-AMS-P-5315, current at revision C of 2022. The drawings are current as AS29513C and AS29512C. The MS part numbers stay valid on drawings.
What compound is an MS29513 O-ring?
A nitrile compound qualified to AMS-P-5315 (formerly MIL-P-5315), the hydrocarbon fuel resistant packing document. Parker ORD 5700 (2021) pairs N0602-70 with it and notes the MS29512 and MS29513 series. Note that this is not the MS28775 hydraulic compound; the two families are different nitriles for different fluids.
