Quick-disconnect couplings

Indi-Lok

Indi-lok couplings provide quick connect/disconnect capability with self-sealing action and superior performance during operation and maintenance of fluid systems.
  • Compatible with all standard and many exotic fluids currently used in today’s high technology aerospace, ground, and undersea systems.
  • Available in a wide variety of temperature and pressure ranges.

  • Recommended where limited access requires visual and/or touch indication and assurance of a fully coupled and safety locked position.

Quick-disconnect couplings

Non-Latching: Automatic

Automatic couplings are recommended for use with today’s advanced precision fluid systems for space flight, aircraft, ground, and undersea applications.
  • Best utilized where space is limited and hands-off operation is required.

Current applications include:

  • Electronic cooling systems
  • Hydraulic accumulators/cylinders
  • Cryogenic systems
  • Brake systems
  • Manifolds

Quick-disconnect couplings

Non-Latching: Sub-Miniature

Sub-miniature couplings offer proven high performance in a very compact size.
  • Designed specifically for use in liquid flow through modules (of Standard Electronics size) and similar constructions.
  • Can be used in even the smallest of plug-in electronics cooling applications.

  • Small envelope, high performance and unsurpassed reliability are key features of Parker Stratoflex non-latching couplings.

Quick-disconnect couplings

Slide-Lok

Slide-Lok couplings are very similar to Indi-Lok couplings except for the mechanical indicators that are present on the Indi-Lok coupling design.
  • Used in a variety of applications including military and commercial aircraft, rocket launching systems, marine applications, Formula-One race cars, and many others

Quick-disconnect couplings

Single-Shut Off Couplings

Single shut-off couplings are recommended for use on fluid systems requiring the self-sealing valving on one side of connections only.
  • Mate with standard fluid fitting ends and other precision aerospace fittings.
  • Available in lightweight aluminum for low-pressure applications and CRES or titanium for high-pressure applications.

Quick-disconnect couplings

Thread-Lok

Thread-lok couplings provide today’s aerospace fluid handling systems with quick disconnect capability, self-sealing action and visual/touch indication of a fully coupled position.
  • Simple one-hand operation and reliable performance for use during the maintenance of fluid handling systems.
  • Thread-together coupling provides the mechanical advantage required for coupling under higher pressures.

Quick-disconnect couplings

Motor Racing QD’s

Motor Racing QD’s are very similar to Indi-Lok couplings except for the mechanical indicators that are present on the Indi-Lok coupling design.
  • Used in a variety of applications including military and commercial aircraft, rocket launching systems, marine applications, Formula-One racecars, and many others.

Break-away

Break-Away Valves

Proven lifesavers, Stratoflex breakaway valves separate under crash loads on fluid lines exceeding a predetermined value.
  • Upon separation, the valves automatically seal the fluids in the lines to effectively prevent spills.
  • Typically used on fuel lines, main fuel tanks, aircraft auxiliary fuel tanks, air-to-air refueling systems, and fall away external tanks.
  • Tank vent lines often use single valve versions.

Hydraulics

Hydraulic fuses & flow regulators

Hydraulics engineers at commercial aircraft OEM’s such as Boeing and Airbus have depended on Waterman hydraulic fuses and flow regulators for many years.
  • Flow regulators limit the rate of flow in hydraulic lines to predetermined ranges, regardless of variations in system pressure or workload.
  • Waterman flow regulators are used to insure proper landing gear operation in most Boeing commercial jets flying today.
  • Hydraulic fuses work much like their electrical counterparts.
  • Hydraulic fuses protect systems from damage due to loss of reservoir fluid or ruptured tubes, hoses, or other components.

A custom part made with a multi-point quality check is just a click away.
