Nai-Lok 1/4" Double-Ended Gas Sample Cylinder 316L Stainless Steel Seamless Sampling System Cylinder

Product Description

NAI-LOK Sampling System Double-ended Gas Sample Cylinder Sampling Cylinder

 

Product Description

The NAI-LOK 316L TPED Compliant Gas Sampling Cylinder is precision-engineered to safely store and transport high-purity or hazardous gas and liquid samples. Manufactured using seamless 316L stainless steel tubing, the cylinder is double-ended with 1/4" FNPT connections, offering exceptional corrosion resistance and mechanical strength.

Designed in compliance with TPED (Transportable Pressure Equipment Directive) standards, this sampling cylinder is suitable for use in petrochemical, refining, and hydrocarbon analysis systems, where safe containment, cleanliness, and integrity are critical.

Ideal for offshore installations, lab environments, and field applications, each cylinder is 100% tested and certified, with optional internal surface finishes such as BA (Bright Annealed) or EP (Electropolished) for ultra-high-purity gas handling.
