623-072-49mp3-crn - 6ft Stainless Steel Cryo Hose, CGA 320 x 1/4" JIC

High-Performance Cryogenic Transfer Assembly

The 6ft Stainless Steel Cryogenic Hose (SKU: 623-072-49MPS-CRN) is a precision-engineered component designed for the rigorous demands of industrial gas transfer. Specifically manufactured for Carbon Dioxide (CO2) service, this hose assembly bridges the gap between high-pressure storage cylinders and distribution manifolds or process equipment. Its construction is optimized to handle the unique challenges posed by cryogenic fluids, including extreme thermal contraction and phase change pressures.

Material Construction and Durability

The assembly features a robust double-layer design. The inner core is constructed to maintain chemical inertness and thermal stability, ensuring that the purity of the gas is preserved during transfer. Surrounding this core is a high-tensile stainless steel outer braid. This braiding serves multiple critical functions: it significantly increases the burst pressure rating of the hose, provides mechanical armor against abrasion and impact in rough industrial environments, and prevents the hose from over-bending or kinking. Unlike rubber hoses that can become brittle and crack under cryogenic conditions, this stainless steel assembly retains its flexibility and structural integrity even when exposed to liquid CO2 temperatures.

Connection Specifications

Precision fittings are swaged onto the hose ends to ensure leak-proof performance. The inlet side features a CGA 320 nut and nipple, the North American standard for Carbon Dioxide cylinders. This connection utilizes a flat washer design to create a positive seal against the cylinder valve. The outlet side is terminated with a 1/4" Female JIC (Joint Industry Council) swivel fitting. The JIC 37° flare is a metal-to-metal sealing standard known for its reliability under vibration and high pressure. The swivel mechanism is particularly advantageous, allowing the operator to tighten the connection without transmitting torque to the hose itself, thereby preventing twisting and stress on the assembly.

Compliance and Application

The inclusion of "CRN" in the product identifier indicates that this assembly carries a Canadian Registration Number, signifying that the design and manufacturing process meet the stringent safety codes required for pressure vessels and piping systems in Canada. This level of compliance makes the hose suitable for regulated industries including medical gas supply, food and beverage carbonation, and heavy industrial welding. Whether used for filling stations, laser cutting assist gas, or shielding gas distribution, this hose delivers consistent, safe, and reliable performance.
