FAQs
What is the main purpose of a brass olive?
A brass olive is a compression ring used in plumbing fittings. It is compressed onto the pipe by tightening a nut, creating a watertight or gas-tight seal between the pipe and the fitting body.
Can I reuse a brass olive?
It is generally not recommended to reuse brass olives. Once compressed, they can deform and may not provide a reliable seal upon reinstallation, potentially leading to leaks.
Is this olive suitable for all types of pipe?
This 15mm olive is specifically designed for use with 15mm copper or brass pipes. It may not be compatible with plastic or other types of pipework.
What does WRAS approved mean?
WRAS (Water Regulations Advisory Scheme) approval means the product has been tested and meets the requirements of the Water Supply (Water Fittings) Regulations 1999 in England and Wales, making it safe for use with drinking water.
How do I know if I've tightened the compression nut enough?
Refer to the specific instructions provided by the compression fitting manufacturer. Generally, tighten the nut hand-tight, then use wrenches to turn it an additional 3/4 to 1 full turn for a 15mm olive, ensuring a secure seal without overtightening.
Can this olive be used for gas lines?
Yes, Primaflow Brass Olives are suitable for gas installations as well as water. However, always ensure compliance with all local gas safety regulations and use appropriate fittings.
Troubleshooting
Olive is difficult to slide onto the pipe
Ensure the pipe end is clean, round, and free from damage. Lightly chamfer the pipe edge if necessary.
Leak detected after installation
Check that the olive was correctly positioned and that the pipe was fully inserted into the fitting. Re-tighten the compression nut according to the fitting manufacturer's instructions. Ensure the pipe is not deformed.
Olive appears damaged or deformed
Do not use a damaged olive. Remove and replace with a new, undamaged Primaflow Brass Olive.

Setup, Compatibility & Care
Setup:
- Ensure the pipe end is clean, smooth, and free from burrs. Use a pipe cutter for a clean, square cut.
- Slide the compression nut onto the pipe, followed by the Primaflow Brass Olive (ensure the chamfered edge faces the fitting body).
- Insert the pipe fully into the corresponding compression fitting body.
- Tighten the compression nut by hand until it is snug.
- Using two wrenches (one to hold the fitting body, the other to turn the nut), tighten the nut further. The amount of turn depends on the fitting manufacturer's instructions, but typically is 3/4 to 1 full turn for a 15mm olive.
Compatibility:
- This 15mm brass olive is designed for use with 15mm copper or brass pipework.
- It must be used with compatible compression fitting bodies and nuts. Always use fittings from a reputable manufacturer.
- Suitable for both cold and hot water systems, as well as low-pressure gas installations (ensure compliance with gas safety regulations).
Care:
- Store olives in a clean, dry place to prevent corrosion.
- Avoid overtightening during installation, as this can damage the olive or fitting.
- Regularly check compression joints in accessible areas for any signs of weeping or damage, especially after initial installation or system pressurization.
