I have an old hose. It is mostly in great condition, one end is twisting and obstructing the flow of water. Some of my other hoses have plastic sheaths to protect them, so I figured I would make my own.

Step 1: Tools/Materials

Tools:

Crescent Wrench
Heat gun
File
Saw

Materials:

PVC pipe
A hose
Teflon Tape

Step 2: Cut to Length

Cut you PVC pipe to length. I cut mine a few inches longer than the part that was bending. After you cut the pipe to length, cut a groove down the middle. The groove will allow the pipe to separate enough to slip over the hose.

Step 3: End

This is not the end of the instructable. "End" refers to the end of the pipe. Cut a "V" with the bottom of the "V" on the line down the middle of the pipe. Use a file to smooth out the "V" into more of a "U". The purpose of the "U" is to reduce stress on one point of the hose.

Step 4: Sand

Sand the PVC pipe to remove any barcodes or words that may be printed on. This step is optional, as it doesn't make it work any better. It only makes it look better. I used 220 grit sandpaper.

Step 5: Heat and Wrap

Using a heat gun, heat up the plastic until it is malleable. You should be able to bend it with your fingers. Once it is at this stage you are going to have to move fast.

Turn off the heat gun
Set it down in a position that will keep the hot tip off anything flammable
Get some thick gloves or paper towel or a rag
Use the above to pry open the PVC pipe, and force it onto the hose.
Hold the pipe closed while it cools

After it cools, you can slide it up into its' final resting position.

Step 6: Attach the Hose

When you attach the hose it is important to use Teflon tape. If you don't, it is likely your hose will leak. As well as using Teflon tape, tighten the hose with a crescent wrench to get that extra tightness.
