Secondary Containment Bushing
Secondary Containment Device for Plan 66A Crude-oil Pipeline Applications
The SCB Secondary Containment Bushing is a standardized, dual-bushing arrangement intended for use in conjunction with API Plan 66A. It is used as the back-up to a primary seal and is usually incorporated into the cartridge. This seal is specifically targeted at crude-oil pipeline pump seals, such as the Type 8648VRS.

Features
- California Residents: PROPOSITION 65 WARNING
- Restricts leakage beyond primary bushing at full pipeline pressure in the event of primary seal failure in both dynamic and static operation to 1500 psi g (103 bar g).
- Enables upset to be detected, switched off, and pump shaft to coast down without significant release to the environment.
- Increases seal mean time between repair in the most difficult crude-oil applications, when used with Type 8648VRS ‘NPSS’ technology.
