BPV-31 - Universal Supco Universal Refrigerator Piercing Valve Accessory

BPV-31 - Universal Supco Refrigerator Piercing Valve Accessory

The BPV-31 Universal Supco Refrigerator Piercing Valve is a genuine Supco refrigeration service accessory designed to provide access to sealed refrigeration systems. It accommodates 1/4-inch, 5/16-inch, and 3/8-inch outside-diameter tubing and provides a 1/4-inch male flare connection. Supco rates the BPV31 to a maximum pressure of 500 PSI.

This universal piercing valve is commonly used by refrigeration and appliance technicians when temporary access to a refrigeration line is required for system diagnostics, pressure testing, evacuation, or refrigerant service. Appliance Kingdom supplies appliance and refrigeration parts across Canada with Canada-wide shipping.

What Does the BPV-31 Piercing Valve Do?

The BPV-31 clamps onto compatible refrigeration tubing and uses a piercing needle to create access to the sealed system. Its 1/4-inch male flare connection allows appropriate refrigeration service equipment to be connected to the system. Supco specifies the valve for 1/4-inch, 5/16-inch, and 3/8-inch tubing.

The valve features a patented gasket design that Supco states provides 50 times more sealing area than competitive O-ring designs. It also uses a precision piercing needle engineered for proper seating and includes a hex key wrench.

Correct tubing size, installation technique, and pressure rating are important when working on a sealed refrigeration system. An improperly selected or installed access valve can result in refrigerant leakage or damage to the tubing.

Common Reasons to Use a BPV-31

The BPV-31 is a service accessory rather than a component that controls normal refrigerator operation. It may be used when a qualified refrigeration technician needs access to a compatible sealed system for purposes such as:

• Connecting refrigeration service equipment

• Checking system pressure

• Performing system diagnostics

• Evacuating a refrigeration system

• Charging or servicing a refrigeration system where appropriate

• Creating temporary service access on compatible refrigeration tubing

Supco specifies the BPV31 for installation on compatible round suction lines or uneven tubing and identifies it for low-side use in R-410 systems.

Will Replacing or Installing This Part Fix My Refrigerator?

The BPV-31 is not a refrigerator control or operating component, so it does not directly repair common refrigerator problems such as poor cooling, excessive frost, or compressor failure.

Instead, it is a refrigeration service accessory that can provide technicians with access to the sealed system so they can diagnose and service the underlying problem. Whether a piercing valve is appropriate depends on the refrigerator, tubing, refrigerant system, and repair procedure.

Compatibility & Ordering Guidance

The BPV-31 is a universal refrigeration piercing valve designed for compatible tubing with the following outside diameters:

• 1/4 inch

• 5/16 inch

• 3/8 inch

Supco specifies a 1/4-inch male flare connection, zinc construction, and a maximum pressure rating of 500 PSI.

Always measure the refrigeration tubing and confirm the application before ordering. Do not select the valve based solely on the refrigerator brand or model.

Supco also states that copper or aluminium tubing is recommended and warns that harder tubing materials can damage the piercing needle.

Installation Overview

Installation of a piercing valve involves working directly with a sealed refrigeration system and should be performed by a qualified refrigeration or appliance technician.

The valve must be installed on compatible tubing using the manufacturer's specified procedure. Proper tubing selection, valve positioning, system pressure, refrigerant handling, and leak testing are important considerations.

Supco specifically notes that solderless piercing valves can develop leaks over time and should not remain on a refrigeration system after completion of the repair.

Because refrigeration systems contain pressurized refrigerant, this is not recommended as a casual DIY repair. Professional installation and servicing are strongly recommended.
