About this product
A PBK-type back-up ring used alongside O-rings to prevent extrusion.
It measures 117.0x123.2-117.8x124.0 mm, with a 117 mm inside diameter and 123.2 mm outside diameter. Support rings should never be mounted on the pressure side.
Product details
| Inside diameter | 117 mm |
|---|---|
| Long description | Back-up rings are 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. |
| Outside diameter | 123.2 mm |
| Product details | Supports rings should never be mounted on the pressure side, Note: The dimensions d and S below are the O-ring dimensions |
