Steel Hex Coupler 1/4" FPT 5000 PSI

Strong, Reliable, and Built for Tough Jobs

The Steel Hex Coupler 1/4" FPT 5000 PSI is built for strength, durability and long life in high pressure environments. Made from steel, this compact connector is designed to perform in industrial, commercial and mechanical applications where safety and consistency matter.

With 1/4" FPT threads on both ends, this coupler ensures a secure and leak free connection every time. The hex shape makes it easy to grip with a wrench, so you can install and remove quickly even in tight spaces. Rated for up to 3000 PSI, this is perfect for hydraulic setups, mechanical assemblies and pressure related systems that require heavy duty nuts, couplers and fasteners.

Built for Strength

The steel hex coupler is more than just a small connector, it’s a critical fastener that ensures proper function and safety. The hex coupling design allows torque to be applied evenly with a standard wrench so the nut is properly tightened without damaging threads or connected parts.

Compared to other options, stainless steel or zinc coatings may provide additional corrosion resistance but plain steel couplers like this are a staple in mechanical work because they are affordable, available and rugged. Many hex coupling nuts are made for specific applications but this one is a general purpose solution.

Coupling Nut Design

A coupling nut is a long nut used to connect two threaded rods or other bolts. This hex shaped fastener is designed to join components securely while allowing precise alignment and adjustment.

• Hex Coupling Nuts: Provide extra length for stability.

• Most Coupling Nuts: Are made to standard dimensions, with variations in width across flats depending on sizes.

• Coupling Nut Finish: Can be plain, zinc or stainless steel for added durability.

This one uses the standard hex shape for secure handling so even torque distribution and reduced risk of stripping threads.

Applications

The hex coupling design is perfect for:

• Joining two threaded rods in construction or repair.

• Connecting bolts where extra length or alignment is required.

• Hydraulic or pressure related applications that need heavy duty fastener performance.* Mechanical setups where two male threads need to be secured with precision.

With the sight hole option (available on some models) you can check if threads are aligned during assembly.

Material, Finish and Options

Made from solid steel for maximum tensile strength. Standard plain finish is cost effective, zinc plated or stainless steel options are available for added corrosion resistance.

• Plain Finish: For indoor use.

• Zinc Finish: For outdoor use.

• Stainless Steel: For harsh environments.

Multiple sizes available, choose the one that fits your needs. In stock or custom builds these hex coupling nuts are strong.

Ease of Use

Hex shape and standard width across flats makes installation easy. With a wrench in hand the coupler can be tightened securely for safety and to prevent failure under load. The two male threads inserted into either side align perfectly for a solid joint.

This design means you can work efficiently without wasting time. The coupler is simple: a durable nut that performs consistently.
