Product Description

The HAM-LET Relief Valve (SKU 3G-OTH-437779) is a non-code pressure relief valve for air, inert gas, and liquids, featuring a 1/4 in MNPT x Let-Lok connection. Constructed from 316 stainless steel, it has a maximum operating pressure of 350 psi (MPN H-995-HP-SS-NL-1/4-A-EP).

Frequently Asked Questions

What is the HAM-LET H-995-HP-SS-NL-1/4-A-EP relief valve used for?

This HAM-LET relief valve is designed for non-code air, inert gas, and liquid pressure relief applications. It protects systems from overpressure by opening at a set point, commonly used in instrumentation, pneumatic controls, and process lines where 316 stainless steel corrosion resistance is required.

What are the specifications of the HAM-LET H-995-HP-SS-NL-1/4-A-EP?

The HAM-LET H-995-HP-SS-NL-1/4-A-EP is a 316 stainless steel relief valve with 1/4 in MNPT inlet and 1/4 in Let-Lok outlet. Maximum operating pressure is 350 psi. It is a non-code type for air, inert gas, and liquids, with an EP (ethylene propylene) seal.

Where to buy the HAM-LET H-995-HP-SS-NL-1/4-A-EP worldwide?

3G Electric supplies the HAM-LET H-995-HP-SS-NL-1/4-A-EP relief valve worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time.

How to select the correct HAM-LET relief valve for my system?

Select based on media (air, inert gas, or liquid), pressure rating (max 350 psi for this model), connection size (1/4 in MNPT x Let-Lok), and material compatibility (316 stainless steel). Verify set pressure requirements and ensure the valve is non-code rated for your application. Consult HAM-LET documentation for sizing.
