68100376 - 1 Inch x 3/4 Inch Brass Hex Bushing - Bar Stock

Reliable Fittings for Shop Fabrication and Repair

Every welder and fabricator knows that a system is only as strong as its weakest connection. When you are plumbing air lines for your plasma cutter, setting up a custom gas manifold, or repairing cooling lines on a spot welder, you need fittings you can trust. The 1" x 3/4" Brass Bar Stock Bushing is the heavy-duty solution for adapting pipe sizes without sacrificing durability. Machined from solid brass rather than cast, this bushing is built to handle the rough-and-tumble environment of a metalworking shop.

Why Choose Bar Stock Over Cast?

Cheap cast fittings are notorious for cracking when you tighten them down, especially if you are trying to get that last quarter-turn to stop a hiss. This bushing is different. Because it is machined from a solid bar of brass, it has a uniform grain structure that resists splitting and cracking. You can torque it down with confidence. The threads are crisp and sharp, biting into the mating part to create a solid metal-to-metal seal that holds up against vibration and pressure fluctuations common in shop air and gas lines.

Essential for Equipment Adaptation

It is a common scenario: you buy a new filter-regulator or a heavy-duty valve, and the ports are 1-inch NPT, but your shop plumbing is running 3/4-inch lines. This bushing is the perfect adapter. It sits flush or nearly flush with the port, taking up minimal space while providing a robust reduction. It is compatible with all standard shop fluids and gases, including compressed air, water, argon, CO2, and nitrogen mixtures.

Installation Tips

The hex head design gives you plenty of surface area to grab with a wrench, ensuring you don't round off the edges during installation. For the best results, always use a quality thread sealant or PTFE tape on the male threads to lubricate the connection and ensure a 100% leak-free seal. Whether you are building a new system or performing emergency maintenance, keeping high-quality bar stock fittings like this in your inventory saves time and headaches.
