WILTEEXS 18709 3/8-Inch Stainless Steel Quick Connect Pressure Washer Adapter Set, Max Pressure 5000 PSI Rating

This coupler pair is good compliment. They connect and disconnect easily. The threads are mill finish. Before using the coupler on the intended devices, use something, such as a brass nipple, that has 3/8 NPT male threads, and fasten these couplers to the nipple. This will smooth the stainless steel threads and ensure that you will not damage the threads on the intended device.

Good Product

I own a professional pressure cleaning company, these are less expensive than most places and work just great. I have an 8 GPM @ 3500 psi and these fit nice without leaks.These see chemicals, soaps etc on a daily basis..Lithium grease them and change your O-rings, and they should last a long time.

Very happy with this purchase so far but may add comments in future. All depends on how it performs.

Low grade stainless, these have corroded faster than the others i've purchased from specialty stores for the same price. I'm using these with commercial strength bleach so your usage may vary. The bearings have also stopped moving freely so I'm having difficulty disconnecting hoses. Wouldn't recommend for professional usage and would only recommend with this disclaimer for general use.

great quality and value

Not the connector that I wanted, apparently nobody makes what I want

Good
