Solid Copper Compression Olives (Pack of 20)
BS EN 1254-2 Standard · 8mm to 54mm (including 12mm, 15mm, 22mm, 28mm) · WRAS Suitable

The MEP Stock Solid Copper Compression Olives (Pack of 20) are trade-grade compression sealing rings manufactured to BS EN 1254-2 standards. When tightened within a standard compression fitting, the annealed copper olive deforms uniformly against both the fitting seat and the copper pipe wall, creating a permanent, metal-to-metal leak-tight mechanical seal for drinking water, central heating, and low-pressure gas services.

Size Availability
8mm, 10mm, 12mm, 15mm, 22mm, 28mm, 35mm, 42mm, 54mm & 3/4"
Complete trade coverage for microbore central heating, 12mm European feeds, and 15mm/22mm mains pipework.

Why Plumbers Prefer Copper Olives Over Brass Olives

Unlike rigid brass olives which require significant spanner torque and risk crushing or ovalising soft copper tube, copper olives are softer and more malleable. Under compression, copper olives compress effortlessly with less torque, forming a flawless leak-free seal without damaging the underlying copper pipework.

Frequently Asked Trade Questions (Compression Olives)
1. What is a 12mm compression olive used for?
A 12mm compression olive is commonly used on European heating and sanitary pipework, imported mixer taps, heat pump capillary pipework, and specialist commercial refrigeration circuits requiring standard 12mm outer-diameter copper tube.
2. Is copper or brass olive better for plumbing?
Copper olives are widely preferred by professional UK plumbers for domestic copper-to-copper installations because copper crushes smoothly into the pipe contour with less tightening force, significantly reducing the risk of hairline leaks or pipe crushing.
3. Can you reuse a copper compression olive?
No. Compression olives are single-use components. Once compressed by the compression nut, the olive undergoes permanent plastic deformation. Reusing an old olive or overtightening will cause persistent weeping joints.
4. Do I need jointing paste or PTFE tape with copper olives?
On clean, new copper pipework, a copper olive creates a 100% metal-to-metal dry seal without compound. However, applying a light smear of WRAS-approved jointing compound (such as Boss White or Fernox) around the olive helps lubrication and ensures total sealing security.
5. What pipe sizes do these copper olives fit?
Our packs of 20 are available for all UK standard metric pipe sizes: 8mm and 10mm (microbore), 12mm (European/tap feeds), 15mm and 22mm (standard hot and cold water), 28mm (boiler primaries), and larger commercial sizes up to 54mm.
