Welding hoses are designed to transport fuel gases such as oxygen and acetylene to welding equipment. These flexible tubes come in twin or single configuration, each carrying its own gas. Welding hoses are also classified by connection size with A, B and C sizes featuring typical nipples with seating surfaces that make use of these connections easier.
Grade R
Grade R welding hoses are frequently used with oxygen and acetylene gas sources. They’re relatively cheap and come in twin lines (green for oxygen & red for acetylene) or single line versions, each featuring ribbed covers to reduce drag while providing added abrasion resistance and oil resistance.
Grade R hose is not recommended for alternative fuel gases like LPG, propane, natural gas and propylene due to its low permeation rating; oils present in these fuels will quickly dry out the hose’s internal fabric layers over time and render it unsafe.
Noting the importance of choosing the appropriate hose size, it is also imperative to remember its significance for safety purposes. Most sizes have either right hand threads for oxy-fuel applications or left-hand threads for fuel gas applications, depending on what torches require; some torches require larger “C”-size connections with maximum working pressure of 200 PSIG so as to provide sufficient gas volume during heavy cutting and scarfing – choosing an adequate working pressure cannot exceed 200 PSIG for safety’s sake as doing so could cause it to rupture or degrade over time – finding an adequate size is of paramount importance when considering safety considerations; otherwise this could cause it exploding or degrading before even starting out!
Grade T
Welders often take for granted and abuse the welding hose, using it for pulling equipment around or even applying pressure to it – yet this rubber pipeline serves an invaluable purpose: safely transporting flammable gases to their torch. Your welding and cutter welders could only exist without it.
Grade R twin welding hoses work great with acetylene but may be inadequate when exposed to new fuel gases which run at much higher pressures compared to acetylene; hence they must be designed specifically for them.
Dayco premium Grade T twin welding hoses are an ideal fit for these new fuel gases, featuring flame and oil resistance with high tensile braided reinforcement for optimal welding applications and offering a 4:1 safety factor for welding applications. Non-blooming properties (which do not secrete combustible oils), wax-free features (do not secrete wax that clogs assembly), 25 foot lengths with B size oxy/fuel fittings complete its features.
Length
A welding hose’s length determines how much gas is transferred between its tank and torch, as well as preventing damage or the build-up of dust or contaminants that reduce its efficiency. A shorter length hose may be better suited to small projects while longer ones tend to be preferred when dealing with larger tasks.
Good quality welding hose is both durable and easy to keep clean, and should be regularly checked for signs of fraying or kinking that indicate wear-and-tear damage. Should any such signs appear, it is vital that you replace it immediately with another.
Welding hoses come in various sizes and connection types, such as A, B and C connections. They’re used for transporting oxygen and acetylene gas for cutting, welding and brazing applications like cutting, welding or brazing applications requiring cutting, welding or brazing operations. Each welding hose is customized for specific application requirements with different working pressure ratings and temperature ratings as well as burst pressure ratings (i.e. how much pressure it can safely withstand before it ruptures).

Welding is a dangerous skill that requires great skill, which exposes welding technicians to extreme temperatures, sparks, flames, toxic fumes, vapors, and gases. Luckily, welding hoses provide an additional safeguard that keeps technicians safe while decreasing risk for accidents or injuries.
At our facility, we carry an assortment of welding hose sizes to meet the demands of any job site. For instance, our “C”size hoses are suitable for gas supply equipment with higher gas volume requirements that requires larger diameter connections; they feature maximum working pressures of 200 PSIG and are compatible with oxygen/acetylene torches.
Our premium twin welding hoses are color-coded to clearly distinguish the type of fuel gas being used – red for acetylene and green for oxygen. Furthermore, these assemblies come complete with factory-fabricated and tested coiled coupled assemblies which feature non-blooming tubes as well as resistance against abrasion, flame, oil and ozone exposure.
