Clear PVC Pipe Cautions

GF Harvel does not recommend the use of this product or other rigid PVC/CPVC piping products for the transportation or storage of compressed air or gases, nor the testing of these systems using compressed air or gases.

Although GF Harvel Clear maintains its physical properties when exposed to many substances, exposure to certain chemicals can affect the clarity of the product over time. Certain nitrogen-containing organics, bleaches, oxidative agents and acids may result in discoloration. Testing under actual use conditions is recommended.

Exposure to sunlight (U.V.R.) will also affect clarity. This can be addressed in sight glass applications exposed outdoors by simply providing an opaque cover attached to the pipe exterior such as a rubber flap or sleeve. These facts should be considered if optimum clarity is required for the system by testing under actual use conditions at the initial design phase of the project.

Standard threading or grooving can be conducted with GF Harvel Schedule 80 Clear pipe. Threading or grooving of GF Harvel Schedule 40 Clear pipe is not recommended due to insufficient wall thickness. Use specialty clear transition fittings for threaded assemblies or standard PVC transition fittings where applicable.
