Copeland 998-0510-37 Service Valve

This one's a documented factory part, not a guess: the Copeland 998-0510-37 shows up directly in Copeland's own 3D-body semi-hermetic compressor service literature as one of the listed service valve options for that platform, alongside the 998-0510-02, -07, -08, and -11 valves covering the other line sizes on the same compressor family. It's a 7/8" service valve (1-3/4"-12 Rotalock-style thread on the compressor side), used for suction or discharge isolation and gauge access on 3D-body compressors and other Copeland models sharing this port size.

Genuine OEM machining means the valve seats correctly against the factory port and holds pressure through repeated gauge connections - not something you can say for every generic replacement on the market. If you're servicing a 3D-series semi-hermetic and need the 7/8" port specifically, this is the documented, correct part rather than a size-matched substitute.

Key Benefits

• 7/8" Line Connection: Sized for standard 7/8" O.D. copper suction/discharge lines.
• Documented 3D-Body Fitment: Listed in Copeland's own service valve reference for the 3D semi-hermetic compressor platform, alongside the 998-0510-02/-07/-08/-11 valves for other line sizes on the same family.
• Gauge Access Built In: Standard service port for manifold gauge connection during charging, recovery, and diagnostics.
• OEM Machined Body: Built to Copeland's factory tolerances for a proper seat and long-term seal integrity.

Common Questions

• What compressor platform is this documented for? Copeland's own 3D-body semi-hermetic compressor service valve chart lists the 998-0510-37 alongside the -02, -07, -08, and -11 valves, which cover the other line sizes used across that same compressor family.
• Is this suction or discharge? The 7/8" port is used on both suction and discharge sides depending on the specific 3D-body model - confirm against your compressor's nameplate or the valve being replaced.
• Will this fit compressors outside the 3D line? Other Copeland models sharing the same 7/8" port and thread may accept it, but the 3D-body platform is the documented fitment - verify against your unit before ordering.
