Seal Kit - FPM Hand Sprayers

This pack includes O-rings of different sizes and a replacement Valve Disc all made from FPM meaning that they have a high resistance to acidic chemicals as well as a resistance to general chemicals. These packs are designed to be used with our CLEANER range of hand sprayers as well as others, from our range of Mesto sprayers, fitted with FPM seals.

It is not always necessary to replace your sprayer. If you have invested in a quality sprayer (which you have if you have bought a Mesto sprayer) then it is worth looking after it. Seals will slowly start to perish, especially those that are used with corrosive chemicals. A failed seal will generally mean that your sprayer leaks or is unable to hold pressure. When this happens, there isn't anything wrong with the sprayer it just means that a seal needs replacing. It is quick and easy to do and, once changed, will give your sprayer a new lease of life.

This pack includes 5 x O-rings as well as a replacement valve disc so you will have a complete set of discs and rings for your sprayer.

How do I know if a seal needs replacing?

It depends which seal needs replacing but generally the sprayer will either start to leak, can't hold pressure or you won't be able to build-up pressure within the tank. These are the common indicators that a seal needs to be replaced and which seal it would be.

What is a Valve Disc?

If you open your sprayer you will see the long compression shaft, which is attached to the head of the sprayer. At the base of this shaft you will see the green valve disc. This acts as a one-way valve so that when you pump the handle it either blocks the shaft, stopping liquid from entering it, or opens to allow air to pass from the shaft into the tank.
