RL935 - Miller Smith RL935 3/16" x 20' Grade R Twin Hose

Technical Overview: Miller RL935 Grade R Twin Hose

The Miller RL935 is a premium-quality twin welding hose designed specifically for oxy-acetylene applications. Manufactured to meet strict industry standards, this hose features a Grade R rating. Grade R hoses are constructed with an EPDM rubber liner and cover, making them suitable for acetylene gas but incompatible with LP gases such as propane or natural gas due to the potential for oil-based degradation. This specific assembly features a 3/16-inch inner diameter (ID), which offers a tighter bend radius and lower physical weight compared to standard 1/4-inch hoses, making it ideal for light-to-medium duty applications where maneuverability is critical.

The hose comes pre-assembled with standard B-size (9/16"-18) brass fittings, ensuring compatibility with the vast majority of industrial regulators and torch handles found in North America. The 20-foot length provides adequate reach for bench work and localized fabrication stations without creating excessive clutter. The exterior is color-coded according to international safety standards: Green for Oxygen and Red for Fuel (Acetylene). The reinforcement layer ensures the hose maintains pressure integrity while resisting kinks and abrasion common in workshop environments.
