Product Questions & Answers

Reckon this check valve would work alright for a small hydraulic system I'm puttin' together? Just need somethin' that can handle maybe 2 GPM and around 1800 PSI.

Question by: Janet E on Sep 22, 2025, 6:12 PM

For a setup like that, this brass inline check valve should do the trick, as it's rated up to 2.5 GPM and 2000 PSI. Make sure that 1/4-18 NPT male connection fits your needs.

what's the cracking pressure on this brass check valve got male NPT threads

Question by: Darryl A on Feb 8, 2026, 5:22 PM

Looking at the specs, there appears to be missing information on the exact cracking pressure value in the product details provided. The valve handles up to 2.50 GPM flow rate and can work with systems up to 2000 PSI, but you'd need the complete specification sheet to get that specific cracking pressure number for your application.

reckon this brass check valve will hold up under 2000 psi without leaking

Question by: Eddie H on Mar 10, 2025, 3:36 PM

It handles pressures up to 2000 PSI, with flow rates going as high as 2.5 GPM, making it solid for inline hydraulic setups where you need reliable one-way flow control.
