Split Ring Spanner for 15mm and 22mm Plumbing Compression Fittings | Double End Open Ring Spanner | Flare Nut Spanner | Crows Foot Spanner | Box End | Plumbing Tool | for Compression Fittings

Product Information

Using a spanner, tighten the nut over the threaded head of the fitting, while holding the fitting with a pair of plumber’s grips. This pressure created by the tightening motion will press down on the olive, causing it to grip the pipe tightly. However, be careful not to exert too much pressure as this could damage the fitting or thread, making the device harder to remove or reposition PTFE tape can also be used as a sealant - a few turns need to be wound over the olive such that they will end up sat between the mating surface between the olive and the fitting:

Available in three sizes, 16mm – 40mm, 40mm – 75mm and 63mm – 125mm. This compact tool is a necessity for all your compression installations and repairs. These are cheap and light, and readily available. However they are usually a poor choice since they are often too short to get adequate leverage, they are also usually a somewhat sloppy fit which risks damaging the nut and also injuring yourself should the spanner slip: Copper and brass olives both work fine. Olives can't be removed from a pipe and reused. Even hand tightening a fitting with an olive inside before the pipe is inserted, is enough to make the olive unusable. Most tool kits will include a set of these. While not the perfect tool, they can be very useful since they will adapt to make a good fit on any nut. If you use them with the correct orientation they also grip harder the more force you apply to them: Compression fittings are very reliable and have been proven over many decades, however sometimes things can go wrong and you end up with a joint that leaks. The common causes are:Again, a clean square cut is important, and any burrs removed. Take great care to protect pipe ends when pulling them under floors etc, since its very easy to scratch plastic pipe and this makes it hard to get a good compression (or pushfit for that matter) seal. If, on the other hand, you are preparing the pipe on a workbench at a good working height and you have pipe cutters and a deburring tool to hand, you won't need any more five minutes to prepare.

Among some of the most common solutions for joining copper pipework are brass compression fittings. These couplings feature an olive or ferrule which bites into the pipe and eliminates the need for soldering. They are most commonly used to join hard copper pipe which generally comes in lengths of 2 to 5 metres. Plastic pipe can be joined with compression fittings, however it is important to use the correct brand of pipe insert to support the end of the pipe, or else the joint may start to leak over time.Note that this may not cure a leak that is caused by a scratch on the pipe under the olive. You may be able to wind a couple of turns under the olive - but this is less easy.

There is no significant difference. Compression fittings designed for liquid will work fine with gas but if you use optional PTFE tape, make sure it is gas grade. In addition, ensure the fittings are accessible and not hidden behind walls or under floors. Are Compression Fittings Reliable? We are currently using Royal Mail Parcelforce and DPD as our delivery providers, all small items will be delivered by Royal Mail, these can take up to three working days to reach you. Sometimes an olive can be removed by tightening an adjustable spanner closely around the pipe, and then using it as a slide hammer to strike the nut or the olive itself and drive it toward the pipe end. Depending on the type of fitting you are making, your copper pipe can take anywhere from 3 to 15 minutes to prepare. Often used as part of renovations for tasks like replacing kitchen taps or bathroom taps, these fittings are reasonably priced and don't require soldering making them ideal for anyone with limited plumbing experience.

Compression joints are designed to be used without any sealant. The nut compresses the olive driving it into the cone shaped profile at the end of the fitting body, causing deformation of both the metal surfaces of the olive and the pipe, zeroing the gap and creating a watertight seal. Diameters can range from 6 to 22 mm and fitting types include tee, elbow, straight and mixed connectors with male or female threads. Compression fittings are frequently used to connect taps and other sanitary ware and feature a fairly basic design. They have a main body (which corresponds to the diameter of the pipe) and two threaded seats where nuts are screwed on. A compression ring, called a ferrule or olive, is designed to fit between the seat and the nuts, and is deformed upon tightening to create a watertight seal. The olive can therefore only be used once, but it is possible to replace it when removing an old compression fitting. An olive splitter takes a different approach by tighenting a sharp edge onto the side of the olive while supporting the pipe from the inside. They cut through one side of the olive without damaging the pipe, allowing it to expand a bit in diameter and slide off the pipe.
