Embrass Peerless Compression Fittings — 15mm Chrome, Reducing Couplers and Copper Olives for UK Plumbers

Compression fittings are a staple of every plumber's toolkit. Whether you're joining copper pipe without a blowtorch, connecting to existing pipework, or making a quick repair in a tight spot, a good compression fitting lets you work fast and leak-free. Embrass Peerless has supplied the UK trade for decades, and their compression range — from standard 15mm couplers through to 22mm reducing connectors and bulk copper olives — covers the everyday jobs that come up on every domestic and light commercial callout.

At APM Electricals we stock the full Embrass Peerless compression range ready for next-day delivery. Here's a look at four of the most-used fittings.

1. Embrass Peerless Compression Coupler CP 15mm

Price: £1.99 inc VAT

The 15mm straight compression coupler is the most fundamental fitting in the box. Two olives, two nuts, and you've got a leak-free joint on copper, plastic, or chrome pipe in minutes — no heat required. The chrome plated (CP) finish makes it suitable for exposed pipework under sinks and basins where appearance matters. Suitable for water supply lines, central heating circuits, and general domestic plumbing. Works with standard 15mm copper tube to BS EN 1057.

When to specify: Joining two lengths of 15mm pipe mid-run, repairing a section of damaged pipe, or extending a supply run to a new appliance.

2. Embrass Peerless Compression Tee CP 15mm

Price: £3.50 inc VAT

A 15mm equal compression tee lets you branch off an existing 15mm supply line without cutting the run. Fit it in the middle of a cold feed to add a spur for a new appliance, or use it to create a hot/cold balanced connection point in a cylinder installation. Chrome finish suits exposed under-counter applications. All three ports take standard 15mm copper olives.

When to specify: Adding a drinking-water branch from a 15mm kitchen cold main, creating a branch for a new WC, or extending a central heating circuit feed.

3. Embrass Peerless Compression Reducing Coupler CP 22mm × 15mm

Price: £2.99 inc VAT

The 22mm × 15mm reducing coupler is one of those fittings you'll use on nearly every bathroom or kitchen installation. It joins a 22mm distribution main down to a 15mm branch without needing a tee-and-reducer combination. Compression on both ends means no soldering, no naked flame, and no hot-work permits needed. The chrome finish blends with visible pipework in consumer units and airing cupboards.

When to specify: Connecting a 15mm branch pipe off a 22mm ring main, reducing at the inlet to a boiler or cylinder, or making a transition between two different-diameter copper runs.

4. Embrass Peerless Compact Compression Olive Copper 15mm (Pack of 100)

Price: £13.71 inc VAT

Olives are the consumable at the heart of every compression joint. When you're refitting compression fittings, re-using an old olive risks a weeping joint — always fit a new one. The Embrass Peerless 15mm copper olives come in a pack of 100, making them cost-effective for contractors and multi-dwelling jobs. Copper olives compress more evenly than brass alternatives and are suitable for domestic water, central heating, and gas (where compatible fittings are used). Keep a pack in the van: you'll reach for them constantly.

When to specify: Routine compression joint maintenance, refitting valve bodies, or wherever a new compression seal is needed after disassembly.

Compression vs Solder: When to Use Each

Compression fittings are the right choice when:

• The pipe is damp or the joint area can't be fully dried for soldering
• A hot-work permit isn't available or the building is occupied
• A future-accessible joint is preferred (compression can be dismantled; solder cannot)
• You're working with chrome or plastic pipe that can't be soldered
• Speed of installation is essential

Solder (end feed or Yorkshire) remains the neater option on new copper systems where flame work is permitted, but compression is the practical go-to for repairs, extensions, and connections to existing systems — and Embrass Peerless quality means you won't get a comeback.
