Molco Joint

Fitting For Light gauge stainless steel tubes for ordinary piping: press-type fitting

Product Summary

[画像]モルコジョイントイメージ

Molco Joint is a mechanical joint compatible with light gauge stainless steel tubes for ordinary piping.

 

Formerly, stainless steel plumbing was expensive, required a special set of technical skills and equipment for installation, and therefore was only used at plants with particular needs and hospitals. Press-type fitting was originally developed in Sweden and Germany and has been adopted in dozens of countries for a half century, establishing its position as a universalized system.

 

In Japan, since its release in 1975, Molco Joint has served various purposes as hot and cold water supply, air conditioning in various houses, malls and office buildings.

Structure

[画像]モルコジョイント構造イメージ

The joint body is made from stainless steel (defined in Japanese Industrial Standards as SUS304, SUS316).

 

IIR(Isobutylene Isoprene rubber) is used for the sealing ring attached inside the joint end. To obtain a consistent, sufficient strength and watertightness, insert the pipe to an adequete depth, and use our authorized press tool for installation.

Features

Molco joint is a product made from stainless steel, a material "highly durable", "human-friendly" and "eco-friendly".

  1. Drastically saves the working hours.
  2. The authorized press tools ensure the consistent installation quality.
  3. Requires no welding work in installation, best suited for renovation.
  4. The cost is reasonable for a stainless pipe.
