Frequently Asked Questions
Do you make leak / pressure testing QRCs for manufacturers in Chennai?
Yes. We design leakage and pressure testing quick release couplings for units in Chennai, tested from 0.1 bar to 350 bar and built to suit any end connection — flared pipes, banjos, tubes, flanges and fabricated profiles.
What testing pressure range do your QRCs cover?
Every coupling is leak-tested before dispatch, with testing facilities from 0.1 bar up to 350 bar depending on the application and seal material selected.
How quickly can Chennai customers get a sample?
Send us the component or connection detail and we’ll quote a sample QRC quickly; our couplings typically raise leak-test throughput 4 to 10 times.
Can you customise a testing coupling for our component in Chennai?
Yes. Give us the port profile, working pressure and test medium and we custom-build the coupling in the right material and seal, so it seals first-time and speeds up your leak-test line in Chennai.
