| Long description | Back-up rings type BU | |
|---|---|---|
| Technical info | Back-up rings are normally used in combination with O-rings. Support rings of the BU type consist of polyurethane or PTFE, which is a harder material than the O-ring itself. We advise reducing the extrusion gap to 0 mm at very high pressures. As standard we supply support rings in polyurethane. Note: The dimensions d and S below are the O-ring dimensions. Show more |
