John Guest Speedfit 3/8 x 3/8 x 1/4 Inch Angle Stop Adapter Valve, Push to Connect Plastic Plumbing Fitting, ASVPP1LF

This item makes installing the filter a snap. However, the filter comes with a similar adaptor, just not the size needed to attach to standard faucet connecters. One would think that since you are paying for an adaptor with the filter it could have an either or situation?

I used this product to my undersink water filter. I particularly like the shutoff valve that will make it easier to change the filter cartridge without turning off the main supply.

I used this to connect RO drinking water system to my under sink water source. Works great and good quality. The plastic piece swivels around the metal piece, making it slightly harder to install.

Bought a new sink and the fitting for my water filter didnt fit the 3/4 connections. Local hardware didnt have these JG fittings, which I needed as my water filter uses the 1/4 plastic tubing. Bought this, and in less than 5 min had my water filter hooked back up.

Works great for adding a water line for the fridge. A lot better quality than the one that it replaced.

My plumber said this piece saved the install of our water system

I used this after reading another review about it..... He was so right! This little adapter makes the job a lot easier and now I have a second shut off for just the under sink filter. It threads right on to the 3/8 faucet connection and then gives you a second shut off and connection point for another device, AND it swivels so you can turn it to the best angle! Worth every dollar. UPDATE, I have now used three of these! They are a great idea!

A product bought on Amazon that actually arrives, actually works and is actually from the right manufacturer!!!

This value worked perfectly and made my job easier installing my water filtration system. Great product would defiantly recommend.

Item was shipped quickly, arrived quickly, and was exactly as described.
