Product description

These are threaded inserts designed to be installed into our round tubing. These feature an all metal construction and a circle fin shape. They're designed to go in and have the fins dig into the tube to help keep them in place.

These are sold as sets of Female Threaded Tubing Inserts or as Male Threaded Tubing Inserts, with the two types sold separately. Male threads are all 1-1/4" Long before being installed into connector, useful length will be shorter and will vary my connector size.

The sizes listed are the Testrite tubing sizes Outside Diameter (OD) that the tube connecting nuts are tested to work with.

These parts are sold in sets of 10 and they are bulk packed. Orders of quantities may all be shipped in one bag or box to minimize packaging waste (e.g. ordering qty 10 we would supply 1 bag or box of 100 pcs).

These threaded tubing inserts are offered in a variety of size and enable adding a female or male thread to the end of your round tube, whether the tube is aluminum or steel. We offer threaded tubing connectors in versions for 8-32 thread, 1/4-20 thread, 5/16-18 thread and 3/8-16 thread in sizes including 5/8" diameter, 3/4" diameter, 7/8" diameter, 1" diameter, 1-1/8" diameter, 1-1/4" diameter, 1-3/8" diameter, and 1-1/2" diameter. Note we do not stock every thread size for every diameter, just those listed.

Be aware, these parts are sold a la carte. They do NOT include installation. You would need to install these yourself in your own tubing assembly. There are a variety of ways to install these. Most importantly, be careful not to hurt yourself or others.

If you want 1/4-20 threaded tubing inserts, 8-32 threaded tubing inserts, 5/16-18 threaded tubing inserts, or 3/8-16 threaded tubing inserts, all designed for a press fit, you may have found the right place! Use with Testrite Aluminum tubing in the diameters listed, or use these as threaded pipe inserts though you'll need to confirm which threaded inserts work with which pipe size. Note all our tubing sizes are nominal sizes, so an insert for a 1" tube works with a 1" x .038" wall tube which has an ID of 1" - .038" -.038" = 0.924", though the flexibility of the fins enable these to work in a nice range of tube sizes or tube and pipe wall thickness.
