NB. The UMO0005 is now replaced by the IU-UM1601 Gas Seal Washer. Please see on this link.
I do have a few left, so if you really want this “O” ring, just get in touch.
UMO0005 United Moulders Gas Seal O Ring is for 1/2″ thread inflators. It can be bought individually or in a Multi Pack which you can find on this link.
It is used on the following UML Inflators as the cylinder gas seal/gasket:
- Pro Sensor Automatic
- Mk5 Automatic
- Pro Sensor Manual
The UMO0005 is fitted 1 per device inside the threaded area of the inflator head.
This O ring helps guard against the cylinder coming loose. After tightening the cylinder, the O ring creates a reverse pressure against the thread. The washer also helps to prevent the escape of gas during the inflation process. Cylinders should be checked regularly to make sure they are secure. It is possible for them to come lose in wear.
More information can be found on the manufacture website.
