3/4" (19mm) Black Universal Reinforced Silicone Coolant Cap With Clamp For bypass heater Vacuum Water Port Protective End Cap Kit

Used this to cap an opening on my 2009 R6 intake box. I think I could've gone a size smaller, but this tightened down well with the included clamp. Cap is thick and well made with no visible delaminations despite the small size, multi layered and tight curvature design.

These are great! I used them a 94 ford 351w. Cut the cross over tubes off the exhaust manifolds and placed this cap on them instead of having to weld the manifolds up. I was leary that they could stand up to the heat of the exhaust but I have put around 1000 miles or so on and have had no issues.

Nice quality, would buy again.

Just exactly what I need it and for a good price and fast shipping 👍This was bought for my 06 mini cooper s

worked perfectly

clamp was a little cheap and had to get a better one.

Good quality. Will last a long time

Bought this for a vq35de to cap off the heater hose lines and the 19mm fits perfectly idk if the clamps hold since I used the factory spring clamps
