Copeland 998-0661-42 Valve Plate Kit

The Copeland 998-0661-42 Valve Plate Kit is the OEM rebuild kit for KAE and KAR model Copelametic compressors. When these units start losing capacity, running high head pressure, or short-cycling under load, worn or cracked suction/discharge reeds are almost always the cause - and this kit puts the valve section back to factory spec in one part number instead of piecing together individual reeds, pins, and gaskets.

It's worth flagging that this kit is specifically for the KAE/KAR variants - Copeland's broader K-series valve plate kit (998-0661-16) explicitly excludes KAE and KAR, covering the rest of the K-model lineup instead. Don't cross these two up; they're not interchangeable even though both are K-series compressors.

Key Benefits

• KAE/KAR-Specific Fit: Machined and specified by Copeland for the KAE and KAR Copelametic compressor variants specifically - not the general K-series kit.
• Complete Valve-Section Rebuild: Valve plate, suction and discharge reeds, reed pins, and gaskets in one kit.
• Restores Lost Capacity: Corrects the head-pressure rise and capacity drop that worn or fractured reeds cause.
• OEM Manufacturing: Built to Copeland's original tolerances, so valve timing and seating match factory specification.

Common Questions

• What compressor does this fit? Copeland KAE and KAR model Copelametic compressors specifically.
• Is this the same as the 998-0661-16 K-series kit? No - 998-0661-16 is Copeland's kit for the rest of the K-series line and explicitly excludes KAE/KAR. Use this 998-0661-42 kit only for KAE/KAR models.
• What symptoms indicate this kit is needed? Reduced cooling capacity, rising head pressure, or short-cycling on a KAE/KAR compressor usually point to worn or fractured suction/discharge reeds.
