It restores suction and discharge valve sealing when reed valves wear, crack, or lose tension, which shows up in the field as reduced capacity, elevated head pressure, or a compressor that short-cycles under load. The kit contains the machined valve plate, suction and discharge reed valves, reed pins, and the seating gaskets needed for a complete valve-section rebuild; the matching \u003cstrong\u003e998-0669-37 complete gasket set\u003c\/strong\u003e covers the head-to-crankcase seal on the same 9R\/9RS body if that gasket is also being replaced during the same service call. Because the 9RS1 platform predates HFC refrigerants, this kit is built for use with mineral oil systems — do not introduce POE oil into an R-22\/R-502 charge without a full retrofit.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eExact 9RS1 Fit:\u003c\/strong\u003e Machined and specified by Copeland for the 9RS1, 15 HP compressor body — not a universal or cross-fit part.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComplete Valve-Section Rebuild:\u003c\/strong\u003e Valve plate, suction and discharge reeds, reed pins, and gaskets in one kit — no separate ordering for reed pins or seating gaskets.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRestores Lost Capacity:\u003c\/strong\u003e Corrects the head-pressure rise and capacity drop that worn or fractured reeds cause on 9R-body compressors.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePairs With 998-0669-37:\u003c\/strong\u003e The correct companion gasket set for a full head-to-crankcase reseal is a known, documented pairing — not a guess.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOEM Manufacturing:\u003c\/strong\u003e Built to Copeland's original tolerances, so valve timing and seating match factory specification rather than an aftermarket approximation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWhat compressor does this fit?\u003c\/strong\u003e The Copeland 9RS1, 15 HP semi-hermetic reciprocating compressor (Copelametic 9R body).\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWhat refrigerants and oil is this rated for?\u003c\/strong\u003e R-22 and R-502 systems using mineral oil — this is a legacy CFC\/HCFC-era platform, not rated for POE oil or HFC blends without a documented retrofit.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDo I need the gasket set separately?\u003c\/strong\u003e The valve plate kit includes its own seating gaskets.
