Product Information

One of the difficulties with compression fittings is that while the nuts are usually a nominal size, there is not agreed standard tolerance between manufacturers. This can make selecting a single universal spanner difficult. Also not all spanner types can be used in all situations. Hence most plumbing kits will have a number of spanners, including at least one adjustable one.

Also means that you have twice the number of positions that the spanner can engage with the nut. This is very handy when there is very limited turning space for the spanner. The pipe needs to be cut square and cleanly, with any burrs removed. Pipes cut with a pipe cutter are much easier to use than those cut with a saw. The pipe needs to be clean and free from contaminants like paint or plaster etc. It does not need to be quite as clean and shiny as required for soldered connections. 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. 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 Available in three sizes, 16mm – 40mm, 40mm – 75mm and 63mm – 125mm. This compact tool is a necessity for all your compression installations and repairs.Note that any sealants used on drinking water must have WRAS (Water Regulations Advisory Scheme) approval for this use.

Compression fittings should be tight enough to create a watertight seal but not so tight that the pipe warps or the thread is damaged as this could encourage leaks and make the fittings much harder to remove later. Proceed with caution. What Should I Do if I Find a Compression Fitting Leaking?

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: The most effective "cure all" sealants are the silicone based "setting" sealants like Fernox LS-X. These will usually seal most problem joints so long as the olive is actually meeting the fitting body when the nut is tightened.

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. Once the nuts are done up hand tight on the joint, an additional half to three quarter turn with a pair of spanners (one on the body of the fitting to hold it still, the other on the nut) is usually adequate to make a seal. If the joint leaks, an additional tightening tweak will normally fix it. Note that over-tightening a joint may actually make it leak. These are far better suited, are long enough to get good leverage and are comfortable to use. The design of the end wraps around more of the nut giving better support and greatly reducing the risk of damaging a nut: The partially "open" end allows the spanner to slip over a pipe, and then slid onto the nut.Slide the compression fitting olive (brass ring) over the first length of pipe, and then lay the nut over that Use of PTFE tape on both olive and threads can be of course be combined to both lubricate and seal.
