Designed for EN pipe, DVGW W534 certified product.
Here you can find 5 major features of the product.
With ordinary method such as threading and/or welding, a high level of skill is required for pipe installation work.
However, in case of O.N. Fitting, just few hours of lectures is enough to start working. Anyone can easily perform the installation work by using dedicated pipe expansion machine.
Thin wall thickness stainless steel pipe is applied.
The tolerance of a pipe is appx. 1% and can be corrected to 0.2 mm or less if expanded with the special tool, even though there is a difference of the pipe. Oval distortion can also be corrected. Such special skills can be performed by just pushing a button just for a few seconds.
Amazing tolerance for stress, bending and shaking.
To a convex shape by using the special expansion tool, after which inserting the fitting and tightening the cap nut compresses the rubber packing and creates a seal that prevents leaks. Also, the rubber packing and the convex shape prevent the pipe from slipping and dropping off, allowing strong shaking, pulling and bending forces to be withstood.
The space for working may be limited when doing repairs and renovation etc.
O.N. Fitting system is light, requiring a minimum number of workers to handle and move in a narrow space.
When assembling into unit at another location and moving them for to installation, there is no need of many workers, contributing cost reduction.
Stainless steel is a nearly 100% recyclable metal. It is not likely to rust and has a long service life. Therefore, it can be recycled many times and does not reduce natural resources.
