The FPT series is Aventics' threaded fitting line — straight unions, tees, elbows, plugs, and thread adapters for pneumatic plumbing where conventional NPT, BSPP, and metric thread connections are specified instead of push-in tubing. The catalog spans port sizes from G1/8 through G1-1/4 with brass and steel body options. The FPT platform serves replacement, retrofit, and traditional plant-air installations alongside Aventics' push-in QR1 and QR2 fitting families.
