OVERVIEW

Keep Your Nozzle Secure with Tweco PMA64RS

There are few things more frustrating in the middle of a weld than a loose or slipping gas nozzle. Not only does it distract you from your puddle, but it can also ruin your gas coverage and lead to porosity. The Tweco 1640-1396 (PMA64RS) Retainer Ring is the simple yet essential fix for this common problem. Designed specifically for Tweco MIG guns, including the popular Spray Master series, this retainer ring acts as a spring clip to hold your nozzle tight and true, right where it belongs.

Over time, the heat and abuse of daily welding can cause your original retainer rings to lose their spring tension or become deformed. When that happens, your nozzle starts to wobble or slide off. Replacing the ring with a genuine Tweco PMA64RS restores that factory-fresh grip, ensuring your nozzle stays put even when things heat up. Made from durable spring steel, these rings are built to handle the tough environment of a welding shop, resisting heat fatigue and maintaining their shape over time.

This convenient 10-pack is perfect for any welder's toolbox or shop supply cabinet. Because these are small parts that can easily be lost or worn out, having a pack on hand means you never have to stop production for a cheap fix. Installation is a breeze—simply snap the old one off and slide the new one on. No special tools are required, and you'll be back to welding in seconds.

Don't settle for loose parts that compromise your weld quality. Trust genuine Tweco components to keep your equipment running at its best. The 1640-1396 retainer ring is a small investment that pays off in frustration-free welding and consistent performance. Grab a pack today and make sure your MIG gun is always ready for the next job.
