  • Sil-phos alloy compatibility ensures strong brazed joints
  • Brass and copper construction resists corrosion in demanding systems

HVAC Access Valve Tee

The JB Industries 31148 is a 1/4 inch access valve tee constructed from brass and copper for HVAC service work. It provides a convenient connection point for pressure checks or refrigerant charging on compatible systems.

Flexible Copper Braze Design

The copper braze tee can be bent, cut, flared, swaged, or pinched to suit specific routing requirements. Extra depth slip-fit braze cups simplify placement anywhere along the line using Sil-phos alloy.

Straightforward Braze Installation

Installation requires standard brazing technique with Sil-phos alloy on clean, flux-free surfaces. Overheating the valve core during the braze process is the most common issue and can damage the sealing mechanism.

Questions about this item

Can the brass or copper body of the 31148 be re-brazed if the joint leaks later?

The copper braze tee can be cut, flared, swaged or pinched and re-brazed with Sil-phos alloy to repair a leaking joint.

What limits how long the 31148 can stay under full system pressure?

The brass and copper construction handles normal HVAC pressures; the practical limit is the pressure rating of the connected tubing and the Sil-phos braze joints.

Does the 31148 generate heat or noise when refrigerant flows through it all day?

The tee has no moving parts and adds no measurable heat or noise; it simply conducts refrigerant at line temperature.
