Technical Data

From the Official Catalogue

Cone-to-cone seal: the 58° male tube cone meets the 60° female cone; the initial line contact widens to an annular area seal as the gland nut is torqued
Only one seal; small end-load area; pressure-energised sealing effect; thermal expansion effects minimised
Leakage paths, even for the smallest molecules, are eliminated with comparatively low torques
Properly tightened, the connection can be broken and remade innumerable times
Weep hole between thread and seat facilitates leak detection and protects the gland-nut thread
Left-hand thread on tube and collar prevents unthreading while the gland nut is tightened
Antivibration connectors increase tubing fatigue life under severe vibration or pulsation; interchangeable with standard connectors
