Parametric BSPP Union Nut / Female Thread Nut Generator – Custom G Thread Coupling Nut

Create your own custom BSPP union nut in just a few clicks.

This model is based on a practical, real-world style round union nut with grip grooves, designed for G / BSPP female threads and technical pipe connections. It is ideal for prototyping, replacement parts, custom adapters, hydraulic and pneumatic projects, and many DIY engineering applications.

Instead of downloading only one fixed size, you can configure the part yourself here:

With the configurator, you can easily customize:

thread size (G / BSPP)
pipe bore / inner opening
overall nut length

This makes it easy to generate a union nut that actually fits your project, whether you need a compact pneumatic fitting, a hydraulic connection nut, or a custom plastic coupling nut for a special build.

Why use the configurator?
Most downloadable models come in only one size. This configurator lets you create a custom BSPP female union nut with the dimensions you need, without modifying CAD files yourself.

Typical applications

BSPP / G thread union nuts
custom female threaded coupling nuts
hydraulic connection nuts
pneumatic fitting nuts
plastic pipe connection nuts
replacement nuts for technical assemblies
prototype parts for machinery, fluid systems, and workshop builds

If you need a different size, a different thread, or another bore diameter, just use the configurator and generate your own version.
