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.
