BR-C80 bellow components replaces previous SLBR-D series components. They have similar installation sizes as John Crane type 670, 676, 680 metal bellow components.
It is designed for petro-chemical and chemical processing when the operating temperature is not very high. Elastomer O-rings (FKM, FFKM, etc.) are used as the secondary seal. For some special purpose applications, an all HC-276, or all TA2 component is an essential requirement.

| Standard | Optional | |
|---|---|---|
| Bellows: | 17-4 PH | HC-276, AM 350, TA2 |
| Secondary Seal: | FKM | FFKM, NBR, HNBR, PTFE-Encapsulated Fluorocarbon, etc. |
| Seal Face: | Antimony Impregnated Carbon Garphite | Tungsten Carbide, SiC, Resin Impregnated Carbon Graphite |
| Ring Adaptor: | Carp. 42 | Duplex, HC-276, TA2 |
| Adaptor: | SS 316L | HC-276, TA2 |
| Non-Concurrent* Limit | ||
|---|---|---|
| Temperatures: |
HC-276: -4oF to 428oF (-20oC to 220oC) 17-4 PH: -4oF to 392oF (-20oC to 200oC) | |
| 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.
