347995 - Push-Lock Hose Nipple, B-Size Water Connection, 3/8-Inch ID

Reliable Water Connections for Your Welding Setup

When you are running high-amperage TIG or MIG applications, your water-cooling system is the lifeline of your torch. A leak in your coolant line can lead to catastrophic torch failure, costly downtime, and a messy shop floor. The ESAB Push-Lock Hose Nipple is the professional's choice for building or repairing 3/8-inch water lines with confidence. Designed to work seamlessly with B-Size water connections, this fitting allows you to create custom-length coolant hoses that are secure, durable, and leak-free.

The standout feature of this nipple is its push-lock design. If you have ever struggled with bulky hose clamps that snag on equipment or cut into your hands, you will appreciate the simplicity of this system. When used with the correct push-lock style hose, you simply lubricate the barb and push the hose on. The barbs dig into the hose liner, creating a seal that actually gets tighter as water pressure builds. This means no clamps are required, resulting in a clean, snag-free hose assembly that looks as professional as it performs.

Built from solid brass, this nipple stands up to the harsh conditions of a welding shop. It resists rust and corrosion caused by water and coolant additives, ensuring that your flow rate remains unimpeded and your connections stay sound year after year. Whether you are hooking up a new water cooler, replacing a damaged section of hose, or retrofitting an older torch system, this ESAB fitting provides the precision and reliability you need to keep your focus on the arc, not on the floor. It is the perfect solution for welders who demand quality components for every part of their rig, right down to the fittings.
