Product Description

NAI-LOK Alloy 400 Seamless Sampling Cylinder 250ml 1/4" FNPT 1800psi for Halogen Gas Sampling
 

Product Description

 

NAI-LOK Alloy 400 Seamless Sampling Cylinder is specifically engineered for halogen gas sampling applications in offshore, petrochemical, and industrial environments. Constructed from corrosion-resistant Alloy 400 (UNS N04400), it offers excellent resistance to hydrochloric acid, chlorine, and other aggressive halogens. The seamless design ensures structural integrity under high pressure, while the 1/4" FNPT connections provide secure and leak-tight integration with instrumentation systems. Its compact 250ml volume is ideal for trace gas analysis or portable sampling requirements.

Features:

 

• Material: Alloy 400 (UNS N04400) delivers long-lasting performance against aggressive media

• Double-Ended Design: Enables sampling from one end and evacuation or pressurization from the other

• Standard Size: 1/4" NPT or Compression Tube end connections

• TPED Compliant: Conforms to international transport safety standards

• Seamless Construction: Reduces contamination and ensures pressure containment

• Cleaned for Service: Internally cleaned and dried for oxygen or inert gas service

• Reusable & Durable: Designed for repeated use in industrial environments

• Leak-Tight Guarantee: Each unit 100% factory tested with nitrogen or helium
