Perfect for my gas system
Having a Bavaria boat, the system is equipped with original fittings compatible with the Gok and finding the right model in a physical store is not easy so my point of reference is SVB.

Matching hose for the gas reducer
The hose was recommended to me by an expert for gas testing, and it did everything it promised. Easy to find in the shop, good price, super-fast delivery, easy installation, and the matching cutting ring was included.
The subsequent gas test was completed without any issues.
I'd be happy to use it again next time I need it replaced!

Hi, the union nut says it is 1/4 inch. Do you know what type of 1/4 inch thread it is? Is it NPT, ACME, UTS? I need to check this is compatible with the rest of my system! Thanks for any help!

I've remove old Gas pipe from Bavaria (2005), It looks identical to products 30083/30084 - "Union Nut plus Cutting Ring", but it's got a right thread at both ends. Was there a change from "Right" thread to "Left" thread at some point? Thanks.

Hello David, a gas throw is always left turning. The clockwise (turn right), are the cutting rings. With cutting rings, you are assembled/cut directly on gas pipes. Sometimes the cutting rings aren´t fell down by a uninstallation, you are able to pull them off with a water pump pliers. So you can see only the gas pipe. Your SVB-team.

Why my GLP gas hose is 20 bar , and the one supplied at SVB is only 10 ?, should be ok?

Answer
Olli V. | Jul 7, 2020

The gaspressure in the hose is only 30 or 50 mbar, so you can sleep well with your 10 bar hose.
