37° Flare Triple-Lok ® Tube Fittings
Triple-Lok® fittings are Parker’s 37° Flare tube fittings and adapters. They meet the requirements of both SAE J514 and ISO 8434-2 and offer the industry’s broadest offering of port ends. The compact Triple-Lok® design has a small metal to metal seal area. This results in a low assembly torque as well as high temperature and high pressure capability.

Ferulok ® Flareless Bite Type Fittings
On a Ferulok assembly, the ferrule bites into the outer surface of the tube with enough strength to ensure its hold and seal the fluid. The quality of the bite is visible upon inspection, which minimizes the risk of improper assembly. Ferulok fittings are well-suited for use with tube wall thickness ranging from medium to extra heavy.

EO / EO-2 Metric Flareless Bite Type
Parker EO and EO-2 metric flareless bite type tube fittings are considered the “world standard’ for many industrial manufacturers requiring dependable, leak-free hydraulic tube fittings.
The EO progressive ring fitting consists of a body, a progressive ring (ferrule) and a nut. The progressive ring has two cutting edges that bite into the outer surface of the tube to ensure its hold and its seal at high operating pressures. Presently, EO fittings are the most widely used bite type fittings in the world.
EO-2 high pressure tube fittings are a more recent development. They include an elastomeric seal on all joints in order to eliminate leaks.
