Product Information

Full details

This 5-pack of Loops pneumatic couplings is designed for professionals and DIY enthusiasts needing to connect metric 8mm pneumatic tubing to 1/4" BSP imperial threads. The key benefit is a reliable, corrosion-free connection for pneumatic systems. A potential caveat is their specific use with nylon tubing. These straight adapter couplings feature durable acetal copolymer bodies, nitrile rubber O-rings, and acetal collets with stainless steel teeth for a secure and long-lasting fit.

FAQs

What type of tubing is compatible with these couplings?

These couplings are designed specifically for 8mm outside diameter (OD) metric nylon pneumatic tubing.

What thread size do these couplings adapt to?

They adapt to a 1/4" BSP (British Standard Pipe) imperial thread.

Can these couplings be used for water or other fluids?

No, these couplings are designed for pneumatic (air) systems only and are not intended for water or other fluids.

What are the bodies of the couplings made from?

The bodies are produced from acetal copolymer, an engineering plastic that is corrosion-free and suitable for pneumatic applications.

How do I disconnect the tubing from the coupling?

To disconnect, push the collet ring inwards towards the coupling body while simultaneously pulling the tubing out.

Are these couplings suitable for high-pressure applications?

While designed for pneumatics, specific pressure ratings should be checked against your system's requirements. They are generally suitable for standard pneumatic pressures.

How many couplings are included in this pack?

This product is a 5-pack, meaning you receive five couplings.

Troubleshooting

Coupling leaks air

Ensure the 8mm nylon tube is fully inserted and seated. Check that the tube is cut cleanly and squarely. Verify the 1/4" BSP thread is tightened appropriately and the mating port is not damaged.

Tubing will not insert

Confirm you are using 8mm metric nylon tubing. Check for any obstructions or damage at the end of the tube or inside the coupling port. Ensure the collet is not stuck.

Tubing disconnects unexpectedly

Verify the tube is fully seated and the collet teeth are engaging properly. Ensure the tubing is not being subjected to excessive pulling forces or vibration that could dislodge it.

Difficulty removing tubing

Push the collet ring inwards towards the coupling body while simultaneously pulling the tubing out. Ensure you are pushing the correct part of the collet.

Pros and Cons

Pros

  • Corrosion-resistant materials for longevity.
  • Provides a secure and reliable connection for pneumatic lines.
  • Easy to use with push-to-connect functionality.
  • Suitable for both professional workshops and DIY projects.
  • Cost-effective solution with a 5-pack quantity.

Cons

  • Limited to use with 8mm metric nylon tubing.
  • Only adapts to 1/4" BSP imperial threads.
  • Not suitable for high-temperature applications.
  • May require a specific disconnect tool for removal (not included).
  • Primarily designed for pneumatic use, not other fluid types.

Setup, Compatibility & Care

Setup:

  1. Ensure the 8mm metric nylon tube is cut cleanly and squarely.
  2. Push the end of the 8mm tube firmly into the open port of the coupling until it is fully seated.
  3. Screw the 1/4" BSP threaded end into the corresponding imperial threaded port.

Compatibility:

  • Tubing: Designed exclusively for use with 8mm outside diameter (OD) metric nylon pneumatic tubing.
  • Thread: Compatible with 1/4" BSP (British Standard Pipe) imperial threaded fittings.
  • Application: Intended for pneumatic (air) systems only.

Care:

  • Keep the coupling free from dirt and debris, especially the collet area.
  • Periodically inspect for any signs of damage or wear.
  • Clean the exterior with a slightly damp cloth if necessary. Avoid harsh chemicals.
  • Store in a dry place when not in use.
