Removing and Replacing U.S. Divers Twin-Hose Regulator Metal Clamps
What Are U.S. Divers Twin-Hose Clamps?
In vintage U.S. Divers twin-hose regulators, small metal clamps, also known as box clips, hold the two halves of the regulator securely together. These clips ensure that the regulator’s internal components remain properly sealed while allowing for maintenance when needed.
Over time, these clamps may wear out, corrode, or become difficult to remove, making proper handling essential. If you’re restoring or maintaining a twin-hose regulator, knowing how to remove and replace these metal clamps safely will help preserve your equipment.
How to Remove U.S. Divers Twin-Hose Metal Clamps
Removing the box clips requires care and the right tools. Follow these steps to ensure a smooth process:
Prepare Your Work Area
- Place the regulator on a stable surface, ensuring that it won’t move while working.
- Position the yoke facing upward for better access to the clips.
Use the Right Tools
- Diagonal pliers or small flathead screwdrivers work best for gripping the clips.
- Wearing protective gloves can prevent accidental injuries.
Pry Off the Clips Gently
- Grip the edge of the first clip with the pliers.
- Carefully pull or pry it off while avoiding damage to the regulator cans.
- Repeat for the remaining clips, working slowly and methodically around the regulator.
Tip: Some older clips may be fragile due to age. If a clip bends or breaks, consider replacing it with a new or reproduction part.
How to Replace the Metal Clamps on Twin-Hose Regulators
Once the internal components are serviced, it’s time to reassemble the regulator and secure the clips.
Align the Regulator Cans
- Ensure that both halves are properly seated before attaching the clips.
- Misalignment can lead to air leaks or improper function.
Position the Clips Correctly
- Place each box clip over the designated slot.
- Ensure the curved side faces outward for a snug fit.
Secure the Clips Firmly
- Using your fingers or pliers, press each clip into place until it clicks securely.
- Double-check that all clips are evenly attached to avoid weak points in the seal.
Alternative Fastening Methods
Later U.S. Divers models switched from box clips to a circular retaining ring with a slotted screw. If your regulator uses this system, follow these steps:
To Remove: Use a flathead screwdriver to loosen the screw, then carefully lift off the retaining ring.
To Replace: Align the ring properly, place it over the regulator halves, and tighten the screw evenly.
Maintenance Tips for Long-Term Performance
Keeping your vintage regulator clamps in good condition extends the life of your equipment. Here’s what to do:
Inspect clips regularly for rust, bending, or breakage.
Use corrosion-resistant replacements if the original parts are too worn.
Store your regulator in a dry place to prevent premature metal deterioration.
Final Thoughts
The small metal clamps in U.S. Divers twin-hose regulators may seem simple, but they are essential for keeping the regulator sealed and functioning properly. Knowing how to safely remove and replace them ensures that your vintage scuba gear remains in excellent working condition.
Whether you’re restoring a classic model or simply maintaining your equipment, using the right techniques will help preserve the legacy of vintage scuba diving.
