Standard Plastic Caps

Carpin offers four standard varieties of a plastic cap: flat head plastic caps, full radius plastic caps; ball glide plastic caps; and multi-gage finned plastic caps.

 

Flat head plastic caps are made of polyethylene and economically designed to close off the tube with sufficient force of an interference fit between the ID of the tube and the OD of the plastic cap.

 

Full radius plastic caps are made of durable nylon and have decorative rounded shape that can be used as a glide on legs that are not perpendicular to the floor

 

Ball glide plastic caps offer a more rugged and tighter fit and are made of durable nylon and also have a decorative rounded shape that hides the cut edge of the tube while also being used as a glide on legs that are not perpendicular to the floor.

 

Multi-gage finned plastic caps are made of economical polyethylene, and because of their finned design, theses multi-gage closures offer greater versatility to fit a wider range of tubing wall thicknesses.

 

Shown below are some common configurations:

 

Flat Head Plastic Caps

 

Flat Head plastic caps economically and simply close off the tube. The caps insert into the tube with force because there is an interference fit between the ID of the tube and the OD of the body of the plastic cap.  Flat head plastic caps are made of economical polyethylene.

 

Custom sizes, styles and colors are available upon request.

Ball Glide Plastic Caps

 

Ball glide plastic caps economically and simply close off the tube. The caps insert into the tube with force because there is an interference fit between the ID of the tube and the OD of the body of the plastic cap. Plastic ball caps are made of durable nylon and have a decorative rounded shape that hides the cut edge of the tube and can be used as a glide on legs that are not perpendicular to the floor. Ball glide plastic caps feature a more rugged and tighter fit to the ID of the tube that better resists dislodging.

 

Custom sizes, styles and colors are available upon request.

Multi-gage Finned Plastic Caps

 

Multi-gage finned plastic caps economically and simply close off the tube. The caps insert into the tube with force because there is an interference fit between the ID of the tube and the OD of the fins of the plastic cap. These caps are made of economical polyethylene. Because of the finned design, the multi-gage closure is more versatile and can fit a range of tubing wall thicknesses.

 

Custom sizes, styles and colors are available upon request.
