Laboratory testing of PFA fittings and FEP/PFA tubing (grooved with an Entegris grooving tool) showed successful results under extreme conditions of heat and pressure. Performance reliability is dependent on the care and caution used in grooving the tube and tightening the fitting properly.
Note: the tubing used must be heavy walled (0.047" to 0.062" wall thickness) and must meet Entegris tubing specifications. 1/8" uses 0.030" wall thickness.
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.
