Brass Compression Rings Olives — Reliable Metric Sealing Rings for Copper Tube Fittings

Leaking compression joints are one of the most frustrating problems a plumber or DIYer can face — and nine times out of ten, a worn or incorrectly sized olive is the culprit. Whether you're a professional tradesperson, a facilities maintenance technician, or a hands-on homeowner tackling a plumbing repair, having the right brass compression rings on hand means the difference between a watertight seal and a costly callback.

Each set contains brass compression olives (also called sealing rings or olives) available in three styles — Standard, Thick version, and Double Compression Ring — covering metric sizes from 3mm up to 20mm (≈0.12" to ≈0.79"), including common inch-equivalent sizes such as 6.35mm (1/4"), 9.52mm (3/8"), 12.7mm (1/2"), and 15.88mm (5/8"). Packs are available in 50, 100, or 250 pieces to suit single repairs or large-scale installations. All olives are manufactured from brass, offering a balance of machinability, corrosion resistance, and reliable compression performance.

These brass compression olives are ideal for connecting copper tube in domestic hot and cold water systems, underfloor heating manifolds, and HVAC refrigerant lines. They are also widely used when replacing worn sealing rings in existing metric compression fittings during bathroom or kitchen renovations, making them a go-to stock item for plumbing contractors and maintenance teams.

🔵 Compatibility Note: These olives are sized by tube outer diameter (OD). Always measure your copper tube OD before selecting a size. Designed for use with standard metric compression fittings (BS EN 1254 and similar). Not intended for push-fit or press-fit systems.

⚠️ Spec Confirmation: If you are unsure which style (Standard / Thick / Double Compression Ring) suits your application, or need to confirm pressure ratings for a specific system, please contact us before ordering.

✅ Key Features of These Brass Compression Rings Olives

🔩Three Sealing Styles — Choose from Standard, Thick version (heavier wall for higher-pressure or vibration-prone lines), or Double Compression Ring (dual-ring design for extra leak protection in gas or high-pressure water applications).
📏Wide Metric Size Range — Covers 3mm through 20mm OD, including inch-equivalent sizes (6.35mm, 9.52mm, 12.7mm, 15.88mm), so one supplier covers your entire metric copper tube compression fitting inventory.
🟡Solid Brass Construction — Brass provides reliable corrosion resistance in potable water and heating systems, with enough ductility to deform evenly around the tube OD during compression for a consistent, leak-free seal.
📦Flexible Pack Quantities — Available in 50, 100, or 250 pieces per order, letting you match quantity to job size and reduce per-unit cost on larger plumbing or HVAC installations.
🔄Drop-In Replacement Design — Dimensioned to fit standard metric compression fittings, making these olives a straightforward replacement for worn or damaged sealing rings without modifying existing pipework.
🏠Versatile Application Range — Suitable for domestic hot and cold water supply, underfloor heating circuits, and light commercial HVAC copper tube connections where metric compression fittings are specified.

❓ Frequently Asked Questions

How do I choose the right size compression olive for my copper tube?

Match the olive size to your tube's outer diameter (OD) — not the bore or nominal size. Measure the outside of the tube with calipers. Common conversions: 1/4" ≈ 6.35mm, 3/8" ≈ 9.52mm, 1/2" ≈ 12.7mm, 5/8" ≈ 15.88mm. When in doubt, go by the OD measurement rather than any nominal label on the tube.

What is the difference between the Standard, Thick version, and Double Compression Ring styles?

The Standard olive is the most common type for general plumbing. The Thick version has a greater wall thickness, providing a more robust seal under higher pressure or vibration. The Double Compression Ring features two sealing rings for applications requiring extra leak protection, typically used in gas or high-pressure water lines.

What pressure rating can these brass compression olives handle?

Brass compression olives generally support working pressures suitable for residential and light commercial plumbing — typically up to 10–15 bar (145–218 psi) depending on tube size and fitting quality. For exact pressure ratings in your specific application, please contact us to confirm before installation.

Can these olives be used outdoors or in wet/corrosive environments?

Brass has inherent corrosion resistance and is generally suitable for damp or outdoor environments when properly installed. In highly corrosive environments (e.g., salt air, acidic water), additional protection or stainless steel alternatives may be advisable. Contact us to confirm suitability for your specific conditions.

Are these compression rings compatible with standard metric compression fittings?

Yes. These olives are designed to work with standard metric compression fittings commonly used in plumbing and HVAC systems. They are generally compatible with fittings conforming to BS EN 1254 and similar metric standards. Always verify the fitting manufacturer's specifications before installation.

Should I reuse a compression olive after disassembly?

In most cases, compression olives should not be reused. Once compressed onto a tube, the olive deforms to create a seal. Reusing it typically results in an unreliable connection and potential leaks. We recommend using a fresh olive whenever a fitting is disassembled and reassembled — which is exactly why bulk packs make sense for ongoing maintenance work.

How many pieces do I need for a typical plumbing project?

Each compression fitting joint requires one olive. For a single repair or small job, a 50-piece pack is generally sufficient. For larger installations — such as a bathroom remodel, heating system, or ongoing maintenance stock — a 100- or 250-piece pack offers better value and ensures you have spares on hand.
