JB Industries LT-456 Piercing Valve
The JB Industries LT-456 is a line piercing valve built for HVAC service work. It fits 1/4 in, 5/16 in and 3/8 in outside-diameter tubing and includes a 1/4 in SAE service port for gauge or hose connection. The aluminium body is rated for a maximum working pressure of 500 psi. Technicians use it to access sealed systems without cutting or flaring the line.
HVAC technicians servicing sealed refrigerant
This valve suits engineers who need a permanent access point on copper or aluminium lines carrying CFC, HCFC or HFC refrigerants. It is not for installers who require a removable Schrader core or a valve body rated above 500 psi. Buyers working on high-pressure CO₂ or hydrocarbon systems should look elsewhere. The single-port design also limits use where multiple simultaneous connections are needed.
500 psi maximum working pressure
The 500 psi rating is the decisive figure for selecting this valve. It covers most common air-conditioning and refrigeration pressures but excludes trans-critical CO₂ and some high-side heat-pump applications. Verify the system’s peak pressure before fitting the valve. Exceeding the rating risks refrigerant loss and component failure.

Questions about this item
Will the LT-456 piercing valve fit the 1/4, 5/16 and 3/8 inch OD copper lines already in my system?
Yes, the valve is made for those three outside-diameter sizes, so it clamps onto the existing tubing without changing fittings.
How can I verify the LT-456 is sealing correctly after I install it?
Pressurise the line up to the 500 psi rating and check the 1/4 inch SAE service port with a gauge; a steady reading and no refrigerant smell confirm a tight seal.
Does the LT-456 package include the valve core and cap for the service port, or must I buy them separately?
The valve ships with the 1/4 inch SAE service port already assembled, including core and cap, so no extra parts are needed for basic installation.
