White PVC Tee / Valve Cover for creating a clean and professional appearance on all pipe tee intersections and valve covers. The top part of the tee / valve cover is solid which allows reducing to a smaller pipe on the top or allowing just the valve stem to stick up outside the cover. Simply cut the top part of the cover to the outside diameter of the smaller pipe or valve stem with a pair of scissors.
1.) Use serrated stainless steel King Tacks which are pressed through the overlapping pieces of the fitting cover and will hold them securely. (Steam, Hot Water, etc)
2.) Use PVC Vinyl Z-Tape to seal the fitting cover to the fiberglass pipe insulation. (Cold Water, Chilled Liquid, etc)
3.) Use Proto One PVC Adhesive to glue the seams of the fitting cover. (Exterior Piping, USDA, Washdown Area, etc)
*Tacks, Vinyl Tape, and Adhesive are sold separately.
Use the link below to view the PVC Size Chart to see what size PVC Tee / Valve Cover you need. The PVC Fitting Size is based on both the size of the pipe and the thickness of the insulation.

VIDEO: HOW TO INSTALL A PVC TEE / VALVE FITTING COVER
*Example: You have a main steam supply pipe that is 2" Iron with 1" thick pipe insulation (2 x 1). The supply pipe then has branches that go to 1-1/4" pipe what you are insulating with 1" thick insulation as well (1-1/4 x 1). The size of tee covers to order is based on the 2" Iron pipe (2 x 1 = #11). You would then cut the closed top of the tee to fit the 1-1/4 x 1 pipe insulation on each tee.

Works nicely, fairly easy to install, and leads to a clean appearance on the pipes. If it is possible, my only suggestion would be to form the PVC so it naturally springs closed a little more (the PVC elbows do this better than the tees) which would make installation easier with the loose piece of fiberglass provided.
The suggestion in one of the excellent videos on this site of putting in the tacks on one side before wrapping around the pipe was a good one. I found it difficult to push them through that first time when wearing gloves since the King tacks are quite small- a trick I used is to put the tack point-up on a table and push the PVC layer down onto it.
*Joe, great advice on pushing the King Tacks into the PVC on a table! ~BIP

These PVC Tee covers are a very good way to make your job look great. I like to install them with the King tacks.
