Product Information

Full details

The PrimaPress 28mm Pressfit End Cap is designed for professional plumbers and contractors working on domestic or commercial copper piping systems who need a reliable, permanent seal. Its primary benefit is the 'leak before press' detection system, which ensures that unpressed connections are identified immediately during pressure testing, preventing future failures. A key caveat for users is that the fitting requires specific M-profile pressing tools for correct installation, meaning it is not suitable for manual hand-crimping methods.

FAQs

Can I use this for gas lines?

Yes, the PrimaPress system is suitable for gas applications, provided it is installed by a qualified professional in accordance with local regulations.

Is this fitting reusable?

No, once the end cap has been pressed onto the pipe, it creates a permanent mechanical joint and cannot be reused if removed.

What is the maximum pressure rating?

The fitting is pressure tested up to 24 bar.

Are these fittings WRAS approved?

Yes, they are WRAS and DVGW approved for peace of mind regarding water safety.

Does the temperature range allow for extreme freezing?

It is rated for temperatures as low as -10 degrees Celsius, which is sufficient for most standard glycol-based heating systems.

Can I use a V-profile jaw if I don't have an M-profile?

No, you must use M-profile jaws. Using incompatible jaws will cause a failed seal and potentially void the warranty.

Troubleshooting

The fitting leaks after pressing.

Ensure the pipe was deburred properly and inserted fully to the pipe stop. Verify that the M-profile jaws were clean and correctly aligned.

The press tool does not fit around the collar.

Confirm that the jaws are M-profile. V-profile jaws will not fit this fitting correctly.

Connection appears loose after pressing.

Check that the copper pipe is the correct diameter (28mm). If the pipe is undersized or deformed, it must be replaced before attempting another press.

Setup, Compatibility & Care

Installation Steps

  1. Prepare the Pipe: Ensure the 28mm copper pipe is cut square, deburred, and free of scratches or debris.
  2. Insert Pipe: Slide the pipe fully into the end cap until it meets the stop.
  3. Pressing: Use an M-profile press tool calibrated for 28mm fittings to compress the fitting onto the pipe.
  4. Verification: Inspect the connection to ensure the press mark is consistent and clear.

Compatibility

  • Pipe Type: Standard copper tube (ensure external diameter is 28mm).
  • Tooling: Must use M-profile jaws. Do not use V-profile or other profiles as this will result in an insecure seal.

Care

Store in a dry environment to prevent oxidation before use. Once installed, the fitting is maintenance-free and designed for permanent service.
