Quick Disconnect Coupling Rockforce RF-SE2-3PF internal thread 3/8" with plastic handle

Rockforce RF-SE2-3PF is a quick disconnect coupling with an internal 3/8" thread and a molded plastic handle, engineered for rapid and reliable connection of pneumatic and fluid lines. The threaded inlet provides a secure mechanical joint while the quick-disconnect mechanism enables fast coupling and uncoupling without tools. The compact design and the plastic handle make manual operation straightforward and reduce the risk of damage to surrounding components during frequent use.

Advantages

The coupling combines a threaded 3/8" internal connection with a push-to-disconnect mechanism for quick line changes. The plastic handle offers ergonomic manual control and prevents direct metal-to-metal contact, improving handling safety. Its construction provides consistent sealing for pneumatic or low-pressure fluid applications and is suitable for environments where rapid tool or hose swaps are required.

Suitable for

• Workshop air lines and pneumatic hand tools
• Maintenance tasks with frequent hose or tool changes
• Low-pressure fluid transfer where a threaded inlet is preferred
• Portable equipment and service carts requiring quick connections

Key specifications

• Connection type: quick disconnect coupling with internal threaded inlet
• Thread size: 3/8" internal thread
• Actuation: manual via molded plastic handle
• Intended media: compressed air and compatible low-pressure fluids
• Construction: metal coupling body with plastic handle for operation
• Application pressure: suitable for standard workshop pneumatic pressures (verify system limits before use)

How to use

Ensure system pressure is relieved before connecting or disconnecting. Screw the coupling into the corresponding 3/8" male threaded port until secure. To connect a mating plug, align and push the plug into the coupling until it locks; verify the engagement by a light tug. To disconnect, operate the molded plastic handle or pull back the collar as designed to release the plug, then remove the plug from the coupling. Inspect seals periodically and replace if wear or leakage is detected.

Usage recommendations

Use the coupling within the recommended pressure limits of your pneumatic system and with media compatible with the coupling materials. Regularly inspect threads and sealing surfaces for wear, and keep the handle and moving parts free of debris to ensure reliable operation.
