CB‑SPS‑3FN‑BE Threaded Hydraulic Quick Coupling

CB-SPS-3FN-BE is a rugged steel hydraulic quick coupler from Carterberg, designed for high-pressure fluid transfer systems operating in oil & gas, drilling rigs, and construction vehicles. With a wing-nut locking sleeve and ACME thread profile, it enables quick manual connection even under residual pressure—without the need for tools.

This model features a dry-break dual shut-off valve, hardened steel core, and nitrile rubber sealing for leak prevention under demanding thermal and pressure cycles. Fully compatible with common interchange standards, it offers an ideal retrofit option for international operations.
