Heavy Duty Tube Connectors
Carpin offers both heavy duty and extra heavy duty tube connectors that convert the end of tubing into a receptacle that accepts threaded stems ranging in size from 1/4-20 up to 3/8-16 sized to fit 5/8" to 2" OD tubing, with metric sizes available upon request.
Heavy duty and extra heavy duty tube connectors are utilized to secure tubing members to other pieces of tubing or to plates and walls. These versatile products are commonly used in ductwork supports, rack units, RV ladders, and cross member attachments.
Carpin's versatile tube connectors feature spring clips constructed from high quality forged carbon steel for maximum retention, with a choice of 1, 2 or 4 spring clips for varying strength and economy. Two sets of angled spring clips allow for easy insert then bite into the ID of the tube to provide extra strong holding power. Our spring clips can also be treated with a special rust preventative coating.
Male heavy duty tube connectors eliminate the need to attach a threaded rod or bolt to the connector since the threaded rod is integrated into the product, providing a one-piece solution. The threaded stem diameter ranges from 1/4-20 to 3/8-16 and lengths range from 1" to 1-1/2", with metric sizes available upon request.
Shown below are some common configurations:
