The valve clamps around a copper refrigerant line and, when the valve stem is tightened with the included hex key, a hardened piercing needle punctures the tubing to create an access port. This lets a technician connect a charging hose or gauge to check pressure, pull a vacuum, or add refrigerant to a system that has no factory service port. It's a staple tool for appliance service and DIY refrigerator\/freezer repair.\u003c\/p\u003e\n\u003cp\u003eFits 1\/4\", 5\/16\", and 3\/8\" outside diameter copper pipes with the included adapters. The access port connection is a 1\/4\" male flare fitting. Rated to 500 PSI maximum, with a patented permanent gasket providing over 180 inch-lbs of sealing force — around 50 times the sealing area of a standard O-ring type valve — pressure tested at 250°F. Corrosion-resistant metal (zinc alloy) construction with a piercing needle engineered for concentricity and hardness to seat perfectly every time. Non-positional mounting requires no separate adapter valve and only 2\" of clearance for installation. Each kit includes the piercing valve, a hex key wrench, and 2 adapters. It replaces AP4502525, BPV31, BPV31D, GPV14, GPV31, GPV38, GPV56, and MPV31.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pom-qa\"\u003e\n\u003cp class=\"pom-qa-label\"\u003eQuick Answer\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eXPARTCO BPV-31 Refrigerant Piercing Valve Kit\u003c\/strong\u003e taps into a sealed copper refrigerant line to add refrigerant, check pressure, or pull a vacuum — no soldering required.

Wear safety glasses and protective gloves before piercing any line. Refrigerant handling may be regulated in your area — certain refrigerants require EPA certification (in the US) to purchase and handle. Never vent refrigerant to the atmosphere. This valve is NOT rated for R410a systems (too high pressure).

Identify the copper line you want to tap and confirm its outside diameter (1\/4\", 5\/16\", or 3\/8\") so you can select the correct included adapter. Clean the section of pipe where the valve will mount to prevent debris from entering the refrigerant line. Ensure the composite seal \"O\" ring\/gasket is properly in place inside the valve. Place the two halves of the valve saddle around the pipe using the appropriate adapter insert for your pipe size. Install and evenly tighten the socket-head screws to clamp the valve body firmly around the pipe. To pierce the line, turn the valve stem clockwise with the included hex key until the needle punctures the tubing, then back the stem out (counterclockwise) to open the port and allow flow. To connect a gauge or charging hose: remove the cap, attach your hose to the 1\/4\" flare port, and open the valve by turning the stem counterclockwise. When finished, close the valve (turn the stem clockwise) BEFORE disconnecting the hose, then reinstall the protective cap. Note: the compact valve needs only 2\" of clearance around the pipe. Tools needed: Included hex key wrench, safety glasses, protective gloves. (Note: to attach a gauge directly to the BPV, a retrofit valve adapter may be required — not included.)\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pom-card\"\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdiv class=\"pom-faq-item\"\u003e\n\u003cp class=\"pom-faq-q\"\u003eWhat is a bullet piercing valve used for?\u003c\/p\u003e\n\u003cp class=\"pom-faq-a\"\u003eA bullet piercing valve (line tap valve) lets you tap into a sealed copper refrigerant line to create an access port — without cutting, soldering, or brazing the line. Most household refrigerators and freezers are sealed systems with no factory service port, so if you need to check the refrigerant pressure, pull a vacuum, or add refrigerant, a piercing valve gives you that access quickly. It clamps around the pipe, and a needle pierces the tubing when you tighten the valve stem. It's commonly used in appliance repair and HVAC service, and by DIYers reviving a garage refrigerator or freezer that has lost its charge.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pom-faq-item\"\u003e\n\u003cp class=\"pom-faq-q\"\u003eWhich pipe sizes does this fit?\u003c\/p\u003e\n\u003cp class=\"pom-faq-a\"\u003eThe BPV-31 fits 1\/4\", 5\/16\", and 3\/8\" outside diameter copper pipes using the included adapters. Before installing, measure or confirm your refrigerant line's outside diameter and select the matching adapter insert. Getting the size right is essential for a proper seal — an incorrectly sized adapter won't clamp tightly and can leak. If you're not sure of your line size, measure the outside diameter of the copper tubing with calipers or a pipe gauge.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pom-faq-item\"\u003e\n\u003cp class=\"pom-faq-q\"\u003eCan I use this on an R410a system?\u003c\/p\u003e\n\u003cp class=\"pom-faq-a\"\u003eNo — the BPV-31 is NOT rated for R410a refrigerant systems. R410a operates at significantly higher pressures than older refrigerants like R-12, R-22, and R-134a, and exceeds the safe working pressure of this valve (500 PSI max). Using it on an R410a system is unsafe and could result in valve failure or refrigerant release. This valve is appropriate for lower-pressure systems using R-12, R-22, R-134a, and similar refrigerants. For R410a systems, use service equipment specifically rated for R410a pressures.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pom-faq-item\"\u003e\n\u003cp class=\"pom-faq-q\"\u003eIs a piercing valve a permanent solution?\u003c\/p\u003e\n\u003cp class=\"pom-faq-a\"\u003ePiercing valves are best thought of as a service-access tool rather than a permanent fixture. They work reliably for tapping into a line to diagnose, vacuum, or charge a system, and the BPV-31's patented gasket provides a much stronger seal than basic O-ring valves. However, for a long-term permanent service port, many technicians prefer to cut the line and braze in a proper Schrader service port. Some technicians have concerns about the very long-term sealing of any piercing valve left permanently on a line. If you leave the valve installed, make sure the stem is closed and the cap is in place, and check periodically for leaks.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pom-faq-item\"\u003e\n\u003cp class=\"pom-faq-q\"\u003eDo I need EPA certification to add refrigerant?\u003c\/p\u003e\n\u003cp class=\"pom-faq-a\"\u003eIn the United States, handling many refrigerants (and purchasing them) requires EPA Section 608 certification, and it is illegal to intentionally vent refrigerant to the atmosphere. Regulations vary by refrigerant type and jurisdiction. The piercing valve itself is a tool that anyone can install, but the refrigerant handling that follows may be regulated. If you're a DIYer, research the rules that apply to your specific refrigerant and location, or have the refrigerant work done by a certified technician.
