Questions & Answers

Is there any tubing that will fit this?

1/4 in

What is the ideal pressure for a dual-fuel vehicle? Is it possible to get a charcoal activated filter in a cartridge?

The majority of 60 pounders

Can 1/4" copper tubing be used with this? What is the flow rate like now that the system is up and running?

The outside diameter of 1/4" copper tubing is the same as that of 1/4" guest tubing. I can't think of any reason it wouldn't work. Copper is approved for use with push connect fittings.

How many gallons per minute do you have?

I'm not sure, I didn't really need it.

Selected User Reviews For Shok Blok SB-FPV-40 Water Filter Pressure Regulator Protection Valve for RO & Filter Systems - 1/4" QC Ports, 40 PSI

DOESN'T WORK IN THE LAST MINUTE
5/5

This is a 40 psi regulator, according to the specs. The output and input both have a pressure of 60 psi. I purchased two of these: one for the house and one for the shop. Purchases should be avoided because they are ineffective. Resubmit with a five-star rating. It now does exactly what it's supposed to do after a few days of running. On a 40-pound output, I'm dead.

Play a game of guessing It does what it says, but instead of having a hammering effect, the water flow is now so slow that filling a glass takes an eternity
4/5

I should've ordered a PSI valve with a higher rating.
