Question by: Brent P on Oct 11, 2025, 6:19 PM

Wondering if this adapter can handle high pressure systems?

Answer by: Customer Support on Oct 13, 2025, 11:32 AM

This adapter is rated for a maximum dynamic pressure of 6,000 psi, so it should hold up in high-pressure applications.

Question by: Rod B on Jun 15, 2025, 9:10 AM

what's the pressure rating on this adapter, and will it hold up on a system running close to its max?

Answer by: Customer Support on Jun 17, 2025, 6:40 AM

Rated for 6,000 psi dynamic pressure, so it has solid headroom for most high-demand hydraulic setups. The steel construction and NBR o-ring seal are both suited to continuous pressure environments, and the o-ring boss end gives you a leak-resistant connection that holds well even under sustained load.
