Copeland 998-0510-34 Service Valve Kit

Smaller line sets need service valves too, and a leaking or seized 1/2" service valve will stop a charging or recovery job cold just as fast as a bigger one. The Copeland 998-0510-34 is a 1/2" sweat service valve kit, sized for the smaller suction and liquid lines common on lower-tonnage commercial refrigeration and light air conditioning compressors.

This is the genuine OEM Copeland kit - machined valve body and stem built to factory spec, not a soft-seat aftermarket substitute that starts weeping refrigerant past the packing after repeated gauge connections. The 1/2" sweat end solders into standard copper line with a normal joint.

Key Benefits

• 1/2" Sweat Connection: Matches standard 1/2" O.D. copper line sizing for a clean solder joint.
• Complete Valve Kit: Full valve assembly for a proper replacement rather than a cap-only fix.
• OEM Machined Construction: Built to Copeland's factory tolerances for reliable sealing under repeated service use.
• Gauge Access Built In: Standard service port for manifold gauge connection during charging, recovery, and diagnostics.

Common Questions

• Is this for suction or liquid line service? 1/2" service valves in this Copeland family are used on both suction and liquid-side ports depending on compressor model - confirm against your compressor's nameplate or the valve you're replacing.
• Does this include the seal or cap? Yes, as a kit this includes the components for a complete valve replacement.
• Will this fit any 1/2" sweat Copeland valve port? Match by both the connection size and the exact part number where possible - Copeland has issued multiple 1/2" sweat valve numbers across its compressor lines that aren't always interchangeable.
