Parker Triple Thread Fitting
NPTF / PTT
Parker Triple Thread (PTT)
Adapters
Parker Triple Thread (PTT) adapters are considered the
original three-piece hydraulic flared fittings. As an improved
fitting design over traditional two-piece flared fittings. Its
use was widespread as a primary hydraulic connection for
various aircraft, industrial and mobile applications. The PTT
30° flare three-piece design paved the progress towards the
standardized 37° connection (through the Joint Industrial
Council – JIC) and later to current standardization initiatives
of SAE and ISO. Its popularity has been diminished by the
more common and standardized 37° flare connection, but
even today certain transportation customers utilize PTT hose
adapters for OEM and MRO applications.

• Hose adapter connection only (no sleeve for tube con-
nections)
