Line Tap Practicals for RAC Students
On a refrigerator trainer or a scrap unit, students fit the valve to the process tube or suction line. They tighten it evenly with the hex key and pierce the line. They connect the blue hose of the Manifold Gauges For Refrigeration Systems to the flare outlet and read the standing pressure.
The clamp is then checked for leaks with Bubble Solution For Leak Detection. Teachers can set the fitted valve beside a brazed-in Access Valve and discuss when each one is the better choice.
Frequently Asked Questions
Which tube sizes does the valve fit?
Copper tube of 1/4, 5/16 and 3/8 in outside diameter. Match the valve to the tube, because a loose clamp will not seal round the pierced hole.
What connects to the outlet?
The 1/4 in SAE male flare takes a standard refrigeration charging hose. Through it the system can be read on a manifold gauge set, recovered or charged.
Why use a piercing valve instead of brazing in a port?
It is fitted without heat, so there is no need to recover the charge first or bring a torch near the appliance. That makes it quick for diagnosis on a sealed system.
Can a piercing valve stay on the system?
It can, but many technicians treat it as a port for the job in hand. When the system is next opened, they braze in an access valve, since a brazed joint is harder to disturb than a clamped seal.
How do I check it for leaks?
Pressurise the line, then wet the clamp, the pierced area and the flare outlet with leak-test solution. Watch for growing bubbles, and tighten or refit the valve if any appear.
