BR-C715 (previously SLBM-F) bellow components have similar installation sizes as EG&G Sealol (John Crane) type 715 metal bellow components. It is designed for high temperature and moderate pressure operating conditions in petro-chemical and chemical processing. Flexible graphite is used as the secondary seal by default to reduce friction and extend the seal life

| Standard | Optional | |
|---|---|---|
| Bellows: | Inconel 718 | -- |
| Secondary Seal: | Flexible Graphite | -- |
| Seal Face: | Antimony Impregnated Carbon Garphite | Tungsten Carbide, SiC |
| Ring Adaptor: | Carp. 42 | Inconel 718 |
| Adaptor: | SS 316L | Inconel 718, SS 304 |
| Non-Concurrent* Limit | ||
|---|---|---|
| Temperatures: | -40oF to 750oF (-40oC to 400oC) | |
| Pressure: | Externally pressurized: Up to 363 psi / 25 bar. | |
| Speed: | Up to 5000 fpm or 25 m/s | |
* These operating limits are non-concurrent. In general, an incease in the seal size, or temperature, or rotating speed can reduce the maximum operating pressure limit of the metal bellow component.
