Hardware: High-pressure Fittings

Don’t be fooled by Brass Hardware. All if our brass hardware is specifically designed for use with High Pressure applications.  All fittings are pre-cleaned for Oxygen use per MH ESR-008.

Use of non rated high pressure hardware may result in injury or death.
All of our hardware have an operating pressure of at least 3,000 psi (207 bar)

NOTE:  You will see big swings in prices on most fittings especially in Brass.
This is due to material and labor price increases.
Some hardware fittings have been discontinued or not available in Brass.
In those cases we have had to switch to Stainless Steel as a alternative, if available.
The lower prices you see on our hardware fittings is most likely older stock.
Everything we order in as new stock has had huge price increases.
