Micro thread sizes and dimensions

One part, fewer leaks

A single machined adapter replaces a stack of two or three, so there are fewer joints to leak and the run is shorter and lighter.

Any shape

Straight, 45°, 90°, street 90, tee, Y, cross or a manifold with up to 8 outlets. Stainless, steel, brass, aluminum or engineering plastics.

Checked before it ships

Threads are checked with go and no-go gauges and every order ships with a certificate of conformance. Pressure test reports on request.

Questions

What pressure is a Luer to Micro thread adapter rated for?

It depends on the size and material. In 303 stainless, the common sizes on this page are rated from 100 to 100 psi, set by the lower rated end. The builder shows the exact rating for your part, including a wall thickness check.

Can I get a Luer to Micro thread adapter as an elbow or tee?

Yes. Choose straight, 45°, 90°, street 90, tee, cross or a manifold, then set the length, bore, material and finish. The price and pressure rating update as you design.

How many do I have to order?

There is no minimum. Single parts start at $120, pairs at $55 each, and the price per part drops as quantity goes up.

How fast will it ship?

Standard orders ship in 2 weeks. 1 week and 3 day delivery are available. Every thread is gauged, and every order ships with a certificate of conformance.

Need a size or shape not listed?

Every combination of 24 standards is available in the builder.
