Continental Contitech 20027170 Grade R Twin Welding Hose

Product Description

The CONTINENTAL CONTITECH 20027170 is a Grade R twin welding hose rated for 200 psi working pressure, designed for fuel gas and oxygen delivery in welding and cutting applications. With a 1/4 inch inside diameter and a 17/32 inch outside diameter, this hose delivers consistent gas flow at the torch. It is constructed to meet ARPM IP-7 standards, making it a reliable choice for professional welding operations. The hose is sold in 1-foot increments with a 25-foot minimum cut length from a 500-foot coil, giving shops the flexibility to cut runs to job-specific lengths.

This twin welding hose is suited for oxy-fuel welding, cutting, and brazing setups in fabrication shops, mechanical contractors, and field service environments. The twin-line construction carries fuel gas on one line and oxygen on the other in a single integrated assembly, which reduces clutter and the risk of line crossover at the torch connection. It performs across a temperature range of -40 degrees F to 120 degrees F, making it appropriate for both indoor shop use and outdoor field work in varied climates.

Installation Notes

Installation and connection of welding hoses should be performed by a qualified welder, pipefitter, or gas systems technician. Shut off all cylinder valves and bleed residual pressure from existing lines before disconnecting or splicing hose. Inspect fittings for leaks with an approved leak-detection solution after connection — never use an open flame. Follow applicable OSHA, NFPA 51, and torch manufacturer guidelines for hose routing, storage, and maximum allowable lengths.
