Customer Reviews (4.6 / 5 · 5 reviews)

George A. ★★★★★

The threads on this 4-inch cam coupler are clean and started smoothly onto my NPT fitting without any binding. I connected it to the hose in seconds by hand, and it holds tight with no leaks at full pressure.

Thomas ★★★★★

I was pleasantly surprised how easily this connects by hand — no tools needed for the camlock. The male NPT threads are clean and it paired perfectly with my existing setup. Exactly what I needed for a dust collection adapter.

Harper E. ★★★★★

The aluminum body feels lightweight but sturdy, and the threads on the male NPT side mated perfectly with my hose adapter without any binding. Hand-tightening the cam arms gave a secure seal on the first try with no leaks.
