20 o/d x 13.0 i/d x 20mm Thick Round Plastic Spacer

Our 20mm outside diameter x 13.0mm inside diameter plastic spacers and washers come in a range of thicknesses, with this particular one being 20mm thick.  Manufactured from a hard plastic (typically HDPE or Nylon), these items are designed to maintain a specific distance / gap / separation, between two components or surfaces.

They'll commonly be used in conjunction with threaded fasteners, which is why you find the internal dimensions normally reflect standard metric thread sizes.  Also referred to as Round Standoff's, Cylindrical Spacers, Circular Spacer Sleeves, Round Hollow Tubes, Bushes, Bushings, Shims or Bearings, these all have an unthreaded clearance hole. 

There's hundreds if not thousands of size variations, which is why we give you the option to sort by Outside Diameter, or you can sort by Inside Diameter.  We can also provide Top Hat Bushes, Shoulder Washers, Bearings and Saddle Washers, all of which can be found within our spacers and washers range.

Q: Hi - Can you tell me if your high density polyethylene spacers are UL rated for fire resistance? We are only able to use UL rated components inside our products. Many Thanks.

A: Hello. We've checked this with our partner factory who have advised that unfortunately these are not UL rated. This is because they are made of HDPE regranulate and there are no material data sheets available for regranulate. Kind regards, BPF
