The end connections available are NPT, BSP/ISO threads (RT, RS, RP, RG), SAE straight thread O-ring seal, butt weld, socket weld, and AN 37° flare.
The two-ferrule design seals through a roll-in locking action: 15° angles close between the rear ferrule and nut and between the rear ferrule and front ferrule, while the front ferrule shoulder stops body expansion and nut jamming.
The vacuum rating is 10-9 torr, tested with a leakage sensitivity of 10-9 scc/s, when used with good quality tubing.
GYROLOK Dielectric Fittings interrupt electrical current flow on impulse lines between a pipeline and a monitoring station, protecting instrumentation from impressed current cathodic protection systems, static electricity, and lightning strikes.
Yes, GYROLOK fittings are available cleaned for oxygen service (suffix HPS 18) and for nuclear service (suffix HPS 90). Add the relevant suffix to the basic part number on the purchase order.
