The 3000 PSI Steel Bushing 1/2" MPT x 3/8" FPT is a seriously tough adapter for when you need to get a high-pressure system running smoothly

Often when you're setting up a high-pressure rig, you'll have to deal with mismatched thread sizes between your pumps, hoses and accessories - but this steel bushing fixes that straight away by allowing you to adapt a 1/2" NPT (female) port to take a 3/8" NPT (male) component.

Unlike those flimsy brass adapters that can bend or shear under high torque or unexpected pressure spikes, this bushing is built from top-grade carbon steel - which is why it's a favourite in heavy-duty applications like hydraulic power units, pressure washer pumps, and agricultural machinery where equipment can get pretty rough. And with its compact hex body, you can fit it in place using nothing more than a standard wrench.

Using a steel bushing gives you a real boost in system reliability, especially when you're working in a job where physical toughness is just as important as pressure resistance. This little component is specifically designed to bridge the gap between different pipe sizes without introducing a weak point into the assembly - so you can be confident the flow of fluid is going to remain smooth and safe.

Features & Benefits

Opting for a steel bushing over a softer metal gives you a host of benefits, particularly in environments where things can get pretty rough. This component's engineered to take the strain, and provides a reliable way to bridge the gap between different pipe sizes without putting too much stress on the system.

The hex head design is specifically intended to allow for maximum torque during installation, which means the threads will bite in properly & give you a leak-free seal. Plus, the steel construction has superior resistance to mechanical stress, so it's less likely to crack if you accidentally whack it with a tool or drop something on it - which is bound to happen on a live site.

This fitting makes your plumbing setup a whole lot neater, allowing for a cleaner, more streamlined arrangement of hoses and valves without the bulk of complex adapter chains.

Tough as Nails: Built from carbon steel to withstand high stress & vibration better than brass or plastic.
Leak-Proof: The precision-machined threads give you a tight, metal-to-metal seal that can handle fluids under pressure.
Compact but Effective: The flush-mount design minimises protrusion, keeping the overall footprint of the equipment small & easy to manage.
Handles the Pressure: Can take significant pressure spikes up to 3000 PSI without deforming or stripping threads.

Key Specs

This bushing is precision-machined to strict dimensional tolerances to ensure it'll work with any National Pipe Thread (NPT) standard - which makes it a versatile addition to any maintenance inventory. The external 1/2" MPT is designed to thread in securely into your pumps, manifolds or other larger couplers, while the internal 3/8" FPT takes gauges, hoses, or smaller fittings.

Rated for a working pressure of 3000 PSI, this fitting is perfect for medium-to-high pressure hydraulic and water systems. The steel material is usually treated with a zinc plating or similar anti-corrosion finish to prevent rust from building up when exposed to moisture - which extends the lifespan of the component even in damp or outdoor conditions.

Inlet Connection: 1/2" MPT (Male Pipe Thread) for installation into larger ports.
Outlet Connection: 3/8" FPT (Female Pipe Thread) for accepting smaller components.
Pressure Rating: Can handle continuous operation at 3000 PSI.
Material: Heavy-duty carbon steel with a corrosion-resistant plating.

Installation & Reliability

Installing this 3000 PSI Steel Bushing is an easy process that'll ensure your system stays stable in the long run. It's a good idea to clean both the male & female threads thoroughly before assembly to get rid of any grit or oil. We recommend applying a high-quality thread sealant or PTFE tape to the 1/2" male threads to lubricate the connection & provide a secondary barrier against leaks.

Using an adjustable wrench or socket, tighten the bushing firmly into place until it's flush or securely seated - the steel construction lets you apply a bit more torque than brass, but do take care not to over-tighten & damage the mating port. Once it's in place, this bushing provides a permanent or semi-permanent solution that resists loosening from system vibration, requiring little to no maintenance beyond the odd visual inspection for corrosion or wear.
