OVERVIEW

Reliable Connections for Your Gas Manifold

When setting up a professional gas distribution system, the quality of your fittings defines the safety and efficiency of your operation. The ESAB 18Z50 Adaptor is engineered to provide a secure link between your shop's piping and your acetylene equipment. If you are running a 3/4" NPT pipe drop for your fuel gas, this adaptor is the essential bridge to your D-style acetylene regulators or station valves.

Built for Safety and Durability
Dealing with acetylene requires equipment you can trust. This adaptor is crafted from solid brass, ensuring it can withstand the rigors of daily shop use while resisting oxidation and damage. The heavy-duty construction minimizes the risk of thread deformation or cracking during installation, giving you peace of mind that your gas lines are secure. Whether you are outfitting a new facility or replacing worn components in an existing manifold, the ESAB 18Z50 delivers the performance professional welders demand.

Seamless Integration
Designed specifically for high-flow applications, this fitting ensures that your gas flow remains unrestricted, supporting heavy heating and cutting torches without starvation. The 3/4" NPT Male thread installs easily into standard pipe fittings, while the D-Acetylene Male end provides a precise connection point for your downstream equipment. Don't compromise on your shop's infrastructure; choose genuine ESAB/Oxweld fittings for a leak-free, compliant, and professional gas setup.

FAQ

The pipe side features a 3/4" NPT (National Pipe Thread) Male connection.

D-Acetylene refers to a specific connection size and geometry used in Oxweld/ESAB gas equipment, typically for larger station outlets or regulators, distinct from standard CGA 510 or 300 connections.

No, this adaptor is specified for Acetylene. Oxygen fittings typically use different thread directions (Right Hand vs Left Hand) and dimensions to prevent dangerous cross-connections.

It is manufactured from solid brass, which is the standard material for non-corrosive gas fittings due to its durability and spark resistance.

While the 3/4" NPT side is universal, the D-Acetylene side is specific to equipment designed to mate with that style. Check your regulator or hose nut specifications to ensure compatibility.

For the 3/4" NPT tapered thread side, an appropriate thread sealant or PTFE tape approved for gas service is recommended. The D-Acetylene side typically relies on a metal-to-metal or gland seal and should not be taped.
