OVERVIEW

Professional Grade Acetylene Hose

The ACT14-25 Single Gas Red Hose is a premium-quality replacement or extension hose designed specifically for the transport of acetylene gas in oxy-fuel welding and cutting operations. Engineered to meet strict industry safety standards, this hose features a Grade R classification, making it suitable exclusively for acetylene gas. The hose is constructed with a durable rubber liner and a robust outer jacket that resists abrasion, kinking, and general workshop wear and tear.

With a 1/4-inch internal diameter, this hose ensures consistent gas flow for stable flame characteristics during welding, brazing, or heating applications. The 25-foot length offers ample reach, allowing operators to move freely around large workpieces without repositioning cylinders constantly. The hose is color-coded red, providing immediate visual identification as a fuel gas line, which is critical for workshop safety protocols.

This assembly comes pre-fitted with standard B-size (9/16"-18) brass fittings. Importantly, these fittings utilize Left-Hand (LH) threads, indicated by the notched nut, to prevent accidental connection to oxygen lines. The ferrules are factory-crimped to ensure a high-pressure seal that meets the demands of industrial environments. Whether replacing an aged hose or setting up a new torch station, the ACT14-25 delivers reliability and compliance.

FAQ

No. This is a Grade R hose designed specifically for Acetylene. Propane and other fuel gases require a Grade T hose, as they can deteriorate the rubber lining of Grade R hoses.

The hose comes with standard B-size fittings, which are 9/16"-18 threads. Being a fuel hose, they have Left-Hand (LH) threads.

The hose is reversible; both ends have the same B-size female fitting. You can connect either end to the regulator or the torch.

This is a single line hose. It carries only the fuel gas. You would need a separate green hose for your oxygen supply.

Standard acetylene hoses are typically rated for a working pressure of 200 PSI, although acetylene itself should never be used above 15 PSI.

Fuel gas fittings have Left-Hand threads (counter-clockwise to tighten) to prevent accidentally connecting a fuel hose to an oxygen regulator, which would be dangerous.

Grade R is for Acetylene only. Grade T is oil-resistant and can be used with all fuel gases, including Propane, Natural Gas, and Acetylene.
