STB08

The STB08 profile is a simple endless / solid back-up ring design, but it is a precision machined component that is used to protect O-Rings and other static and dynamic seals where system pressures are greater than the capabilities of the seal alone or where high temperatures and excessive clearance / extrusion gaps are present.

The STB08 is available to suit all standard O-Ring gland sizes including BS1806, BS4518, AS568, ISO3601, JISB2401, MS27595 and almost any custom size you may require.

This part is available in many of our PTFE, Fluoropolymer, thermoplastic and thermoplastic elastomer materials to suit every application, talk to our technical team to discuss your requirements.
