The assembly measures 2-1\/8 in. in diameter and consists of a cast iron\/steel cage body with a three-arm spider retainer (marked \"C-5\" and \"COORS\"), a spring-loaded poppet with yellow elastomer seal, and a machined aluminum cup\/retainer — all loosely assembled per factory packaging as noted on the OEM box. The \"C-5\" designation on the spider retainer indicates the valve cage grade\/class, while the yellow seal is consistent with a Buna-N or urethane compound used in oilfield mud and fluid service. This AR valve assembly is designed to prevent rotation of valve components under high-cycle reciprocating pump conditions, ensuring consistent seating and extended service life in National Oilwell Power Wave fluid end applications. Made in the U.S.A. per the original OEM packaging from TPCI, Odessa, TX.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid #85c94f;padding-bottom:6px;\"\u003eProduct Specifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;\"\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eManufacturer\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eNational Oilwell (NOV)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003ePart Number (OEM)\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e0040-AR-005A-03\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eCross Reference \/ Catalog #\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e100SD0503\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eDescription (OEM Label)\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eGD AR Valve Assy.
