Sanitary Union DIN Blind Liner SS304 SS316L Unions Fitting

1. Brief Introduction of Products:

A blind nut with chain (also known as a blank nut, cap nut, or blind cap) is a hygienic end-cap used to seal open ends of sanitary union piping systems. They are standard components in the DIN Fittings + Sizes | ARCHON Industries and SMS (Swedish Metric Standard) hygienic markets.

2. What It Does?

• Seals Open Lines: It screws onto a male threaded ferrule to securely seal a pipe or hose, typically supported by a flat or D-profile gasket. 

• The "Blind" Design: Unlike a traditional nut with a hollow center that connects two pieces of tubing together, a blind nut is closed at one end to act as a solid, leak-resistant cap.

• The "Chain" Security: The chain loops around the adjacent pipe or equipment. This prevents the heavy, solid-metal nut from being misplaced, dropped, or lost when the line is opened for cleaning or processing.
