BECA 008P Rod

BECA 008P Rod
BECA 008 PTFE

Description

The BECA 008P Rod profile is a back-up ring cut at 30°, which has a concave shape that allows it to fit snugly against the O'Ring. The ring is systematically assembled in tandem with an O'Ring and an X'Ring. An uncut version of this profile can be made.

Advantages

Used in static and dynamic applications
May be used for alternating movement applications
Large contact surface area, which protects the O'Ring from deformation caused by pulsating pressures
Preferred assembly in a closed groove for profiles cut at 30°
Assembly in open groove for uncut profiles

Technical data

Temperature

-200°C/+260°C

Pressure

< 250 MPa in static applications
< 20 MPa in alternating applications

Speed

2 m/s in alternating applications
