Common Applications

The ICE-JLY is a dedicated air-pressure leak tester for custom PC water cooling loops. It connects to any open G1/4 port on a reservoir, fitting or block, then pressurizes the entire dry loop using the integrated hand pump and gauge so you can verify every joint and o-ring before introducing coolant. Hold pressure for at least 30 minutes and watch the gauge for any drop. Always test with the system unpowered and the loop sealed at all other ports. Working on a dry, depressurized loop avoids the spills and short-circuit damage that occur when leaks are discovered with coolant already inside.

Frequently Asked Questions

Q: How much air pressure should I apply when leak testing?

A: For consumer PC water cooling components, pressurize to roughly 0.4-0.5 bar (about 6-7 PSI) and hold for 30+ minutes. Higher pressures can damage acrylic reservoirs and soft tubing.

Q: How does it connect to my loop?

A: It threads into any standard G1/4 port on a fitting, reservoir fill port or block. All other ports must be capped or plugged so the loop is fully sealed.

Q: Do I run the pump or PSU while testing?

A: No. The loop must be dry and the PC powered off during a pressure test. Coolant and electricity are only introduced after the loop holds pressure with no measurable drop.

Q: What does a slow pressure drop mean?

A: A slow leak, usually at a fitting, o-ring or block seam. Re-seat fittings, re-tape NPT adapters if used, and retest. Do not fill the loop until pressure holds steady.

Q: What's in the box?

A: One ICE-JLY leak tester unit with integrated pressure gauge and hand pump, threaded into a G1/4 male fitting for direct connection to your loop.
