DIN/BS/CGA Stainless Steel Cylinder Connecto
The DIN/BS/CGA Stainless Steel Cylinder Connector is designed for high-pressure gas systems, constructed from premium stainless steel for superior corrosion resistance, durability, and long service life. Compliant with international CGA/DIN/BS standards, it ensures secure connections between compressed gas cylinders, regulators, or transfer lines. Ideal for industrial, medical, laboratory, and energy applications.
Standardized Connection: CGA (Compressed Gas Association) compliant for global compatibility.
High-Pressure Rated: Maximum working pressure 3000 psig (207 bar).
Robust Material: Stainless steel construction resists corrosion and wear.
Leak-Proof Seal: 1/4" NPT male thread ensures a tight, secure fit.
Wide Compatibility: Suitable for inert and reactive gases (O2, N2, Ar, etc.).
