Gosknor BPV-31 Piercing Valve Kit 10 pcs — zinc alloy self-piercing valves with adapters & hex keys

This kit supplies ten BPV-31 self-piercing valves plus matching adapters and hex keys, engineered to swap into common refrigeration service ports without needing special tools. Built from zinc alloy and steel, the components are compact and corrosion-resistant for repeated use and straightforward onsite maintenance. The set is packaged to cover multiple repairs or routine parts stocking, and sizes match widely used tubing diameters.

How does this kit fit existing refrigeration lines?

The BPV-31 valves are designed to thread into standard service ports and pierce thin-walled tubing reliably, creating a sealed access point without soldering. Two adapter sizes are included so you can match 1/4", 5/16", and 3/8" outer diameter tubing quickly. Each valve’s center hole is sized to accept standard service fittings and tools.

• Includes 20 adapters to fit 1/4", 5/16", and 3/8" tube ODs
• Piercing valve dimensions: 4.3 x 3.6 x 2 cm with 0.8 cm center hole
• Self-piercing design avoids solder or brazing during installation
• Adapters length: 1.7 cm for reliable seating

What materials and build quality can I expect?

The valves and adapters are cast from zinc alloy for a balance of strength and corrosion resistance, while the included hex keys are steel to resist wear during repeated tightening. The finish and mechanical tolerances aim to withstand routine HVAC and refrigeration service conditions, though users should inspect parts when swapped from inventory.

• Zinc alloy valves and adapter bodies for durability
• Steel hex keys (5.8 x 2 cm) for consistent torque application
• Compact construction minimizes interference with adjacent fittings
• Packaged quantities reduce downtime by having spares on hand

How easy is installation and what tools are required?

Installation is straightforward: position the valve, tighten with the supplied hex key to pierce the tube wall, then secure the adapter as needed. Because each valve comes with its own hex key, you don’t need to provide a special wrench for basic swaps; however, a torque driver and leak detection method are recommended for professional installations.

• Each valve includes a dedicated hex key for immediate installation
• Self-piercing mechanism eliminates need for soldering tools
• Compact size allows work in tight service areas
• Recommended to verify seal with standard leak detection

Who is this for: technicians, facility maintenance teams, and HVAC or refrigeration hobbyists who need a small bulk supply of reliable piercing valves for repairs and system modifications. The pack of ten valves with extra adapters and keys is ideal for service vans, shop spare parts, or routine preventive maintenance schedules where fast, tool-minimal replacement saves time. Note that measurements are approximate; confirm compatibility with your specific fittings and always follow safety and refrigerant-handling regulations during installation.
