Why this product matters

Late Friday arvo, supermarket cool room showing warm temps and a tiny suction line crack. Tech kneads External, wraps the leak, waits for initial set, and the case temps start dropping again. System stays stable overnight; permanent pipe section replacement is done first thing Saturday. Result? Zero stock loss and no grumpy manager. She’ll be right.

For a full leak-finding workflow, pair this with our refrigerant leak detectors to pinpoint and verify repairs before hand-over.

Pro tip

Clean and degrease the pipe before application for best adhesion. After wrapping, you can accelerate curing with gentle heat (heat gun ~5 min) to cut total dry time to about an hour for handling. Gloves on, mate.

FAQs

Is this a permanent fix?
It’s a tough, long-lasting external seal that’s ideal for emergencies and uptime. For long-term compliance, schedule a permanent repair (e.g., pipe section replacement/braze) when practical.

How long to cure?
Allow ~24 hours for full cure. Need it faster? Warm with a heat gun for ~5 minutes to reach ~1 hour handling.

Can I use it on high-side lines?
Yes, observe the pressure guidance (approx. 57 bar at 1 mm; 40 bar at 5 mm) and always verify with a pressure test.

What prep is required?
Clean and dry the surface thoroughly. Degreasing is key to adhesion and fewer call-backs.
