Gosknor BPV-31 Piercing Valve Kit — 10pcs Replacement Valves with 20 Adapters & 10 Hex Keys for HVAC/Refrigeration

Gosknor 10pcs BPV-31 piercing valve kit is a full replacement set containing 10 piercing valves, 20 adapters, and 10 hex keys designed for fast, durable repairs on refrigeration and HVAC lines. This compact repair pack gives technicians and DIYers a ready supply of replacement BPV-31 piercing valves compatible with a wide range of service fittings (TJ90BPV31, AP4502525, BPV31D, GPV series, MPV31, etc.). Constructed from zinc alloy with steel hex keys, the kit balances corrosion resistance and mechanical strength for routine maintenance or emergency swaps. The parts are sized for common tube diameters and include adapters to fit several outer diameters, reducing the need to source multiple single-fit valves.

What components come in the Gosknor BPV-31 replacement kit?

The kit includes everything needed to replace piercing valves on-site: 10 piercing valves, 20 adapters for multiple tube sizes, and 10 hex keys for installation. Packaging supplies enough parts for several service calls or longer-term stock in a service van.

• 10 BPV-31 piercing valves (zinc alloy)
• 20 adapters to fit 1/4", 5/16", and 3/8" outer diameters
• 10 steel hex keys for valve actuation and tightening

How do these valves fit different tubing sizes?

Adapters included with the valves allow secure seating on 1/4", 5/16", and 3/8" outer diameter lines, so you can use one kit across multiple systems. The center hole and adapter dimensions are sized to maintain service access while minimizing refrigerant loss during installation.

• Piercing valve overall size: 4.3 x 3.6 x 2 cm
• Center hole diameter: 0.8 cm to accept service probes
• Adapter length: 1.7 cm to create proper fit on different tubing

Are these valves durable enough for repeated use and fieldwork?

The body components are zinc alloy to resist corrosion, while supplied hex keys are steel for strength during repeated tightening. They are intended as service parts for repairs and seasonal maintenance rather than permanent line installations that require brazing or welded fittings.

• Zinc alloy valve bodies for corrosion resistance
• Steel hex keys for reliable torque during installation
• Compact, robust construction suitable for on-site repairs

How easy is installation with the Gosknor BPV-31 kit?

These piercing valves are self-piercing and designed for quick installation with the included hex keys—no special tooling is required beyond common service tools. That makes them a practical choice for routine diagnostics, temporary service access, or quick component swaps in the field.

• Self-piercing valve design for faster installation
• Each valve includes a matching hex key for immediate use
• Compatible with multiple valve model numbers to simplify stocking

Who is this for This kit is intended for HVAC and refrigeration technicians, service contractors, and knowledgeable DIYers who need a dependable set of replacement piercing valves for maintenance, troubleshooting, or short-term service connections. If you maintain systems using 1/4", 5/16", or 3/8" lines and require a versatile, field-ready parts kit, the Gosknor BPV-31 pack supplies multiple fittings and adapters to reduce downtime and multiple parts orders.

Note: Sizes are measured manually and may vary slightly; monitor and lighting differences may cause minor color variation.
