Copeland 998-0510-31 Service Valve Kit

When the service valve itself is shot - not just the cap or seal, but the valve body - you need a complete replacement, not a patch. The Copeland 998-0510-31 is a 5/8" sweat service valve kit, giving you the full valve assembly needed to restore proper isolation and gauge access on the compressor.

Genuine OEM Copeland manufacturing means the valve seat and stem are machined to factory spec, so it holds a proper seal under refrigerant pressure instead of weeping past the packing gland within a season like a lot of generic replacements do. The 5/8" sweat connection solders in with a standard joint - no special prep or non-standard fittings required.

Key Benefits

• 5/8" Sweat Connection: Matches standard 5/8" O.D. copper line sizing for a clean solder joint.
• Complete Kit: Full valve assembly, not just a cap or seal replacement, for a proper valve-body swap.
• OEM Machined Seat and Stem: Built to Copeland's factory tolerances for reliable long-term sealing under system pressure.
• Gauge Access Built In: Standard service port for manifold gauge connection during charging, recovery, and diagnostics.

Common Questions

• Is this a suction or discharge valve? Copeland uses 5/8" sweat valves on both suction and discharge service ports across several compressor lines - confirm against the compressor's nameplate or the part you're pulling before ordering.
• How is this different from the 998-0510-06 valve? Both are 5/8" sweat, but Copeland lists this SKU as the complete "kit" version - if your old part number matches 998-0510-31 specifically, order this one rather than substituting by size alone.
• Does this include the seal cap? Yes, as a kit this includes the components needed for a complete valve replacement, not just the bare valve body.
