## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect fit for iSpring WSP-50SL
*by J***F on June 19, 2025*

I bought this fitting for an iSpring WSP-50SL under sink water filter. It needs two fittings, 3/8 compression male and 3/4 in NPT male. Not many such fittings are on the market. This set includes 5, which is more than I need. But buying 1 or 2 is not cost effective. I hope they do offer more options. Anyway I'm satisfied with the quality of this fitting.

### ⭐⭐⭐⭐⭐ nice fittings!
*by G***S on May 16, 2024*

Fits tubing and pipe perfectly!

### ⭐⭐⭐⭐⭐ Fitment is very good
*by S***Y on December 20, 2023*

Fitment to mating sides is very good. Threads are formed very well with no seizing or interrupts.
