Product Information
Full details
This Plumbright 28mm Compression Equal Tee is designed for plumbers and DIY enthusiasts working on central heating and hot & cold water systems. Its key benefit is the fast, heat-free installation process, requiring no soldering. A potential consideration is that while joints can be dismantled, ensuring a secure re-fit is crucial for leak prevention. The fitting is manufactured to EN1254 Specification, WRAS approved, and pressure tested to 16 bar.

FAQs
What is a compression equal tee?
It's a plumbing fitting used to join three pieces of pipe of the same size (28mm in this case) in a 'T' configuration. 'Equal' means all three connections are the same diameter. 'Compression' refers to the method of joining, which uses a nut and olive (ring) to create a seal without heat or soldering.
Can I use this on gas pipes?
No, this fitting is specifically designed and approved for water (hot & cold) and central heating systems only. It is not suitable for gas installations.
How tight should I make the compression nut?
Tighten the nut firmly with wrenches after hand-tightening. A common recommendation is 1 to 1.5 turns past hand-tight, but refer to specific installation guides or the product packaging for precise torque figures if available. The goal is a secure, leak-free seal without deforming the pipe excessively.
What does WRAS approved mean?
WRAS (Water Regulations Advisory Scheme) approval signifies that the product has been tested and meets the high standards set by UK water regulations for use in contact with public water supplies. It ensures the material does not contaminate the water.
How long is the guarantee period?
This product comes with a standard 1 Year Manufacturing Guarantee.
Can I reuse an olive from a previous installation?
It is strongly recommended not to reuse olives. Olives are designed to deform onto the pipe and fitting to create a seal. Reusing one can lead to an unreliable or leaking joint.
Troubleshooting
Leak from the joint
Ensure the pipe is fully inserted, the olive is correctly seated, and the compression nut is tightened sufficiently. Check for damage to the pipe or olive. If the pipe is wet, ensure it's dry where the olive seats. Consider re-tightening or, if necessary, replacing the olive and re-making the joint.
Difficulty tightening the nut
Ensure the threads are clean and free from debris. Check that the correct size nut and fitting are being used. If the pipe is slightly deformed, attempt to re-round it before insertion.
Fitting does not seal on wet pipe
Ensure the pipe surface where the olive will seal is as dry as possible and free from debris. A slight stream of water is often acceptable, but pooling water can prevent a seal. Use a cloth to temporarily dry the critical area during tightening.
Pros and Cons
Pros
- Fast and simple installation without soldering.
- Can be used on wet pipework, minimizing system downtime.
- Joints are dismantlable and rebuildable for easier adjustments.
- Suitable for a wide range of domestic water and heating applications.
- High pressure rating (16 bar) ensures durability.
- WRAS approval confirms suitability for drinking water systems.
Cons
- Requires careful tightening to ensure a leak-free seal.
- Compression fittings can be bulkier than soldered fittings.
- May not be suitable for extremely high-vibration environments without proper support.
- Dismantling and re-assembly require care to maintain joint integrity.
- Not intended for use with certain aggressive chemicals or industrial fluids.
Setup, Compatibility & Care
Setup:
- Ensure the pipe ends are clean, free from burrs, and of the correct diameter (28mm).
- Unscrew the compression nut and place it onto the pipe.
- Place the olive (compression ring) onto the pipe, ensuring it is seated correctly against the pipe end.
- Insert the pipe fully into the fitting body.
- Slide the compression nut up to the fitting body and tighten it by hand.
- Using two wrenches, tighten the compression nut further. One wrench holds the fitting body, and the other turns the nut. Tighten according to the manufacturer's recommended torque or until a firm resistance is felt. *Over-tightening can damage the olive or pipe.*
Compatibility:
- Compatible with 28mm copper, brass, or plastic pipes conforming to relevant standards for central heating and hot/cold water supplies.
- Ensure the pipe material is suitable for compression fittings.
Care:
- While the fitting itself requires no maintenance, ensure surrounding pipework is properly supported to prevent stress on the joint.
- Periodically check for any signs of leaks, especially after initial installation or system pressure changes.
- If dismantling, clean the pipe end and olive seating area before reassembly.
