9-4090 - Tweco 10ft Hose Assembly, B-Size LH Fittings

Reliable Replacement Hose for Your Welding Setup

Keep your welding equipment running cool and efficient with the Tweco 9-4090 Hose Assembly. Whether you are setting up a new water-cooled rig or replacing a cracked, leaking hose on your existing machine, this 10-foot assembly is the professional's choice for durability and fit. Welding shops can be tough on equipment—hoses get stepped on, dragged across concrete, and exposed to hot sparks. Tweco hoses are built to take that abuse, ensuring you don't lose valuable arc time to a burst line or a leaky fitting.

This specific hose features Left Hand (LH) B-Size fittings. In the welding world, left-hand threads are the safety standard for water coolant lines (and fuel gases) to make sure you never accidentally plug a water hose into your argon gas regulator. It's a simple but vital safety feature. The 10-foot length is perfect for connecting your water cooler to your torch or extending your reach without creating a tripping hazard with too much slack. The fittings are factory-crimped, meaning you don't have to mess around with hose clamps or repair kits that might fail under pressure.

Don't let a $20 leak ruin a $500 torch. If your current coolant line is showing signs of dry rot, cracking, or stiffening, swap it out with this genuine Tweco assembly. It connects easily to standard 5/8"-18 LH outlets found on most water coolers and welding machines. Trust Tweco quality to keep your coolant flowing and your torch cool, so you can focus on laying down perfect beads.
