Push-fit and compression fitting packs compared
What is actually in the 15mm push-fit and compression packs Wickes sells, how those packs differ, and why they are packs of one fitting rather than a mixed kit.

The guide to push-fit, compression and soldered joints explains how each joint works. This page is about what you buy: the 15mm packs Wickes lists, and what each pack does not contain.
On 13 November 2026 we did not find a mixed assortment that puts push-fit and compression fittings in one box. The products below are packs of one shape. Check the pack quantity on the day, because a title and a feature line do not always agree on other fittings.
Water pipes only. Gas pipes, gas fittings, boilers and gas appliances are for a Gas Safe registered engineer. See when to call a Gas Safe engineer. Copper gas pipe can look like water pipe. If there is any doubt, stop.
Push-fit packs and compression packs
| Pack | Joint | What the listing says is in it | Pipe Wickes names |
|---|---|---|---|
| JG Speedfit equal elbow, pack of 10 | Push-fit | Ten 15mm equal elbows | Copper, and Speedfit PEX or polybutylene. Plastic pipe needs an insert |
| JG Speedfit equal tee, pack of 5 | Push-fit | Five 15mm equal tees | The same |
| Primaflow compression elbow, pack of 2 | Compression, nut and olive | Two 15mm elbows | Copper. PEX only with a pipe insert |
| Primaflow compression equal tee, pack of 5 | Compression, nut and olive | Five 15mm equal tees | The same |
Push-fit is the pack to read when you want a joint with no spanner and no heat, and you may want to take it apart later. Compression is the pack to read when the rest of the run is already compression, or you are happy to use two spanners. Pipe types covers copper, PEX and barrier pipe. The tool kit guide covers cutters.
What the push-fit listings add
Wickes describes both Speedfit packs as demountable without tools, with a collet and a twist-and-lock nut, for hot and cold water and central heating. The same features list gives three pressure figures: cold water 12 bar, hot water 6 bar, central heating 3 bar. Those are Wickes's figures for these fittings, not a pressure you should set a system to.
Plastic pipe still needs the insert the fitting maker specifies. A pipe that is not cut square, or not pushed fully home, is a common reason a push-fit joint fails later. The joint guide explains that. This page does not repeat the method.
What the compression listings add
Wickes describes the Primaflow elbows and tees as nut-and-olive fittings, fitted with a spanner, with no heat and no solder. It recommends them for copper, and says they can be used with PEX if a pipe insert is fitted. The features lists we read do not give bar figures for these two packs. Do not borrow the Speedfit figures and apply them here.
The olive makes the seal. PTFE tape explains why tape on an olive is not usually the answer. White water tape and gas tape are different products. Nothing on this page is for gas.
Soldered joints are not in these packs. Where a joint will be hidden in a wall or floor, the joint guide explains why many people leave that to a plumber, including the rule on lead-free solder for drinking water.
Before you buy a pack
- Match 15mm to the pipe you are cutting. A 22mm run needs a 22mm fitting. These packs are 15mm.
- Buy inserts with plastic pipe, not as an afterthought.
- Shut the water off at the stopcock or an isolation valve before any pipe is cut. Have a bucket ready.
- If the pipe might be the gas supply, stop and ask a Gas Safe registered engineer.
Fitting packs at Wickes
We haven't tested this. Figures are as the maker states them (checked 13 November 2026).
JG Speedfit PEM0315W equal elbow, 15mm, pack of 10. A push-fit elbow pack. Wickes says it suits copper and Speedfit PEX or polybutylene (inserts required), for hot and cold water and central heating, and lists cold water at 12 bar, hot water at 6 bar and central heating at 3 bar.
JG Speedfit PEM0215W equal tee, 15mm, pack of 5. The tee equivalent. Wickes gives the same pipe types and the same three pressure figures.
Primaflow brass compression elbow, 15mm, pack of 2. A nut-and-olive elbow. Wickes says to fit it with a spanner, with no heat, and recommends copper, or PEX with an insert. No bar figure is given in the features we read.
Primaflow brass compression equal tee, 15mm, pack of 5. Five equal tees for joining three 15mm pipes. The same copper-or-PEX-with-insert wording as the elbow pack. Again, no bar figure in the features we read.
Is a push-fit pack as good as a compression pack?
They do different jobs. Wickes sells them as separate packs, not as a tested pair. Use the joint the rest of the pipework and the fitting maker allow, and follow that maker's instructions. The joint guide is the explainer.
Do these packs include pipe inserts?
The listings say inserts are required for plastic pipe. They do not say the inserts are in the pack. Buy the insert the fitting maker specifies.
Can I use these on a gas pipe?
No. These are water and heating fittings as Wickes describes them. Gas work is for a Gas Safe registered engineer.
