Why use a dedicated cleaner?
Pipe and fittings pick up dirt, grease and moisture on site. Cleaner removes these contaminants so solvent cement can bond directly to the plastic.
How to use
- Cut the pipe square and deburr it.
- Apply cleaner to the outside of the pipe end and inside the fitting socket.
- Let it evaporate.
- Apply the correct cement for your pipe type and assemble.
Why clear?
A clear cleaner leaves no visible stain, which is ideal for exposed pipework where appearance matters. If your local code requires visible primer, use a purple primer instead.
Pair it with
- Weld-On 790 multi-purpose cement for PVC and CPVC
- Tangit or Lanco cements for PVC
Safety
Use with ventilation, keep away from flames, and close the can tightly after each use.
