Introduction

Cylinders intended to contain compressed, liquefied or dissolved gas under pressure are fitted with

accessories (valves, straight or angle fittings) to allow release of and refilling with gas. Hereinafter, the

term “valve” applies to such accessories.

The connection between cylinder and valve is obtained by the assembly of two parallel threads with
