@fplsafetyshawn: Ever wonder how grooved pipe couplings actually work? Mechanical couplings are one of the most common methods of joining pipe in fire protection systems. In this video, I break down the key components of a grooved coupling and take a look at how they work together to create a seal. A simple component with some interesting engineering behind it! #FireProtection #FireSprinkler #GroovedCoupling #MechanicalCoupling #Piping #FireProtectionEngineering #FPLSafety
Mechanical engineer here. That was a very nice video. Everything you said was correct. I’ve worked for two different manufacturers of those same couplings in your hand.

Those suck slip coupling way better

The quick Vic is faster for field work. Also a noteworthy point is always use duck butter (pipe joint lubricant) when installing these type of couplings so the casing doesn’t pinch the gasket as you’re tightening that clamp.

Slip couplings are more expensive but slowly becoming the new standard. They are SUUUUPPPPEEERRR fast in the field for install.

how long will the seal hold?

I appreciate this video as a fire protection hybrid alarm/ sprinkler. Before the pipe fitters drop their colon on my statement, Can someone educate me on the difference between groove couplings and slip couplings??? Are slip couplings approved for fire??? Are they better, of course, in your opinion.
please message more info

The gasket is called something. I had to replace them once and their called something specific. I can’t remember. Good video.

Great video. I'd bet 90% of sprinkler fitters don't know how the gasket actually works.

Good information as always. Keep it going.

We put in multiple systems in 1 warehouse where all the bolts for those couplings were defective and when we were testing our system the bolts started blowing apart all over the place! So basically the head of the bolts just couldn't handle the pressure and snapped off!

Don’t know how they work and don’t care

Agree slip coupling so much better

I don't perform this type of plumbing but I 3 been on 1000s of ladders and genie lifts above drip ceilingsnand I have never seen these leak
