Klucz do zaworu butli

Service wrench for cylinder valve with "silencer".

Length 29,5 cm.

An ideal instrument to remove water and replace the o-ring under the valve, and to perform the annual inspection of the inside of the cylinder on your own.

The wrench is made of thick-walled tubing protected by zinc plating against harmful external influences.

On one side it has a DIN G 5/8' thread, and on the other a convenient knurled handle that allows you to tighten or loosen the valve at the cylinder.

On the other side of the DIN G 5/8' thread, the wrench has an M17 female thread into which the screw is screwed.

Between the knurled handle are eight holes, allowing gas to escape.

Inside the wrench, at your discretion, you can insert a hard sponge, which will go some way to reducing the noise made when quickly draining the breathing medium from the cylinder.

The best way to reduce noise, when draining the cylinder, is to wrap the handle of the wrench with a towel.
