Pipe Thread (NPT) Assembly Procedure
-
Apply PTFE tape or paste sealant to MNPT threads starting one thread back from end of fitting.
- When using tape, tightly wrap in direction of threads to conform tape to thread shape.
a. Use 3-1/2 to 4 wraps of tape when assembling PFA threads to PFA material.
b. Use 4 to 5 wraps of tape when assembling PFA threads to a material other than PFA. -
Thread the fitting onto the mating component until hand tight.
-
Using a wrench, tighten fitting about 4 turns past hand tight.
PTFE tape = 1/2" wide for all NPT fittings
Note: PTFE tape is not recommended for use in a gaseous application.
