Features:
- Conforms to TT-S-1732.
- Recommended procedure for sealing pipe threads: We DO NOT recommend using pipe tape. Pipe tape enlarges the outside diameter of the male thread and may cause the female thread to split. We recommend using a pipe thread sealant. Use on clean tapered threads. Apply a thick even coat on male threads using brush applicator. For pipe diameters smaller than 1 1/4" apply to male threads only. For 1 1/4" and larger sizes apply to both male and female threads. Avoid applying amounts. Hand tighten joints and then torqueanother 1/2 to 3/4 turn until threads seal.
