GENERAL INFORMATION:
Pipe Thread Sealant - Warranty is void when Teflon tape is used to seal pipe threads. This is because Teflon tape is a
friction reducing agent which allows customers to over-torque fittings. We recommend using a sealant that does not include
friction reducing agents i.e. Lead Plate.
