Product Description

CB-SPS-3FN-FD86 Thread-to-Connect Hydraulic Coupler

The CB-SPS-3FN-FD86 is Carterberg’s advanced thread-to-connect hydraulic quick coupling, engineered for high-impulse systems where pressure surges and fluid cleanliness are critical. Based on a dry-break, wing nut/hex nut configuration, it ensures secure connection and minimal fluid loss—even when operating under back pressure.

Designed for industries such as mining, hydraulic tool systems, and bulkhead-mounted fluid transfer, this coupling features a tubular valve structure and metal-to-metal secondary sealing, offering robust performance up to 5000 PSI.

Key Features

•  Thread-to-Connect with Wing or Hex Nut
Enables connection under pressure (up to 750 psi) without fluid blowout risk.
•  Dry-Break Valve Design
Minimizes fluid loss and prevents air inclusion during connection/disconnection.
•  Teflon Back-up Rings + Metal-to-Metal Sealing
Ensures high impulse resistance and long seal life, even under thermal cycling.
•  Acme Thread Profile
Resists galling, enhances alignment, and supports repeated connection in harsh environments.
•  Steel Flange for Panel/Bulkhead Mounting
Optional flange simplifies integration into rigid system assemblies.
