Great coupler, great price!
Perfect fit, exact replacement for my old one. Haven't run my machine long with it yet, but it holds up under supercharger pressure and heat on my Waverunner (with aftermarket intercooler installed). Installation was easy, and the material stretches just enough to make the perfect connection.

Worked As Needed
Used this to connect my dust collection system to a recently acquired Jet bench grinder; it fit as needed, so all good.

E46 330i
Exactly what I needed to adapt e46 330 MAF sensor to SLG m50 manifold intake boot. Perfect size, decent price, easy install, holding up good for the past year.

Nice coupler if smell is not important
This a nice coupler if smell is not that important. Unfortunately, the smell does matter for my application. As we know, real silicone does not smell and I don’t know why this piece does. Maybe there are additives, such as dyes, in it.
