The working principle of stainless steel press fittings is to insert thin-walled stainless steel pipe into the socket of press fittings, and use special clamping tools to clamp stainless steel pipe in the pipe fittings. The cross-section shape of the clamping place is mostly hexagonal. In addition, there is O-ring seal between the stainless steel pipe and the fittings, which makes it have the characteristics of anti-leakage, anti-pull out, anti-vibration and anti-high pressure. Therefore, it is an advanced connecting type in potable water system, tap water system, heating system, steam system, industrial oil pipe system and industrial gas pipe system. It is suitable for water, oil and gas pipeline connection.

Currently we have below three series with material 304 and 316L for stainless steel press fitting M & V profile:
