Hoses are used across industries to transfer various types of fuel gases for welding and cutting. Fuel gases such as acetylene, propane, and butane utilize different types of welding hoses. These hoses may differ in terms of their lengths and thicknesses; however, they are commonly distinguished based on their connection sizes – A, B, and C. A welding hose is made of three parts – a swivel nut, a nipple with a seating surface, and a hose clamp or ferrule. The seating surface of the nipple is designed such that it matches with the internal seat of the regulator or torch connections. A clamp helps lock the gas on the hose end of the nipple. The connection sizes are standardized by the Compressed Gas Association of the US. What is the best connection size for oxy-acetylene welding hoses or oxygen welding hoses? Read the post to know the answers.
Typical Uses of A, B, and C Size Hose Connections
Each A, B, and C connections have a typical hose stem, connecting nut, and ferrule. The “B” size nipple is distinguished by its screw-type stem; however, “A” size nipple with its push-type stem. The following are the typical uses of A, B, and C size connection for gas welding hoses.
All welding and cutting hose connection sizes discussed here are designed for a maximum working pressure of 200 PSIG. The choice of the right connection type will depend on your application requirements. It is always recommended to use the right hose connection for your gas welding hoses, preferably sourced from the manufacturer of the equipment. Rexarc is one of the leading manufacturers of acetylene gas plants and gas cylinders in the US. The company is also one of the leading station drop manufacturers in the US, providing A, B, and C type welding hose connections to meet the application requirements of its customers.
