With a robust pressure rating of up to 300 psi depending on application and size they are built for demanding conditions and can perform reliably at a minimum temperature of -30C.
While designed to seal connections effectively the Flexmaster joint requires external restraints such as hangars guides and anchors to prevent movement as they are not intended to hold systems together.

Question by: Wayne M on Sep 15, 2025, 6:07 AM
got a little wiggle in my line up, how much angle will these Flexmaster joints tolerate?
Answer by: Customer Support on Sep 16, 2025, 4:48 PM
For the bulged, straight-through joint style, they will handle up to 4 degrees of angular misalignment per end. If you are using tees, elbows, or crosses, the misalignment limit is up to 2 degrees per end.
Question by: Rusty C on Jun 11, 2025, 12:29 PM
these come in a self-restrained style, does that mean I don't need to use hangers or anchors with em?
Answer by: Customer Support on Jun 12, 2025, 3:05 PM
The self-restrained style does grip the pipe or tube using a stainless steel ring inside the gasket, which keeps the joint from sliding along the pipe. That said, the joint itself is not built to hold the overall hydraulic lines system in place. You still need your normal hangers, guides, and anchors to keep the system from moving. The grip ring handles joint-level retention, not system-level restraint.
