PVC- Cap 2" (Furniture Grade White) DO NOT use these fittings for plumbing projects. Non threaded Flat top caps add a professional look to your PVC project. They are used for the ends of legs on tables and dog beds to keep dirt out of the ends of your pipe. If you want to attach your pipe to a surface, the flat end allows you to drill a hole in the cap and screw it onto the surface. 2" Fittings fit on 2" Schedule 40 PVC or Furniture Grade PVC. Please check out ourPVC Sizing Guide (Specification Sheet)to make sure that you order the correct size PVC Fittings. PVC is NOT measured by the outside diameter, and doing so will result in receiving fittings that are too big for your pipe. Furniture Grade means this fitting has a non-marked, glossy finish.
