Available in different tube sizes, from sub-miniature to one inch in aluminum alloy, stainless steel, titanium and other exotic materials. They meet SAE Aerospace Standards AS4251,AS5072/1/2/3.
The Parker Stratoflex’s Thread-Lok Quick Disconnect (QD) valved couplings provide a proven solution for fluid conveyance systems for aerospace and derivative markets when envelope and weight are important and robust performance is critical. Applications range from hydraulic, fuel, and cooling systems to pneumatic, air data systems, landing gears, wheel and brakes hydraulic fluid motors, military ground vehicles and space applications. Their respective Thread-Lok Ground Service Equipment (GSE) Quick Disconnect (QD) couplings are intended for use with fluid conveyance systems providing a robust connection for ground service equipment to the aircraft flight systems. The Thread-Lok QD is used in a wide range of pressure and temperature applications.
They integrate a highly reliable and robust positive locking mechanism to ensure the performance needed in difficult aircraft system environments such as the engine nacelle, landing gear and brake systems, and other QD demanding installations . The Thread-Lok QD couplings can be used in a wide range of pressure and temperature applications while they provide a simple one-hand operation to thread the QD halves together with a visual confirmation of proper and full coupling to improve both time and safety.
The Thread-Lok QDs incorporate tang and slot design, with QDs engaging and locking in one position when the coupling halves are threaded together and fully connected, providing both visual and touch indication of the fully connected position. They use Parker’s efficient, self-sealing valve design that permits fluid flow with minimum pressure loss and turbulence.
Available in different tube sizes, from ¼ to one inch. Their stainless steel construction meets typical electrical bonding requirements.They meet or exceed MIL-C-25427 and AS1709 specifications.

PARKER STRATOFLEX Non-latching Automatic Self-Sealing & Thread-Lok Quick Disconnect (QD) Couplings
Non-latching automatic self-sealing and Thread-Lok Quick Disconnect (QD) valved hose couplings are manufactured by the Stratoflex Products Division of Parker Hannifin Corporation.
Stratoflex non-latching automatic self-sealing couplings are designed for use in diverse applications like electronic cooling systems, hydraulic accumulators/cylinders, brake systems, manifolds, vapor cycle and cryogenic systems. Automatic couplings are best utilized where space is limited, and hands off operation is required. Small envelope, high performance and unsurpassed reliability are key features of Stratoflex non-latching couplings.

The Parker Stratoflex’s Thread-Lok Quick Disconnect (QD) valved couplings provide a proven solution for fluid conveyance systems for aerospace and derivative markets when envelope and weight are important and robust performance is critical. Their robust performance in harsh environments, their small size, light weight, and high reliability make them a preferred choice. Thread-Lok Ground Service Equipment (GSE) Quick Disconnect (QD) couplings are also offered for use with fluid conveyance systems providing a robust connection for ground service equipment to the aircraft flight systems.
They use the same high performance internal valve design from the IndiLok and SlideLok QDs, and provide a highly reliable and robust positive locking mechanism to ensure the performance needed in difficult aircraft system environments such as the engine nacelle, landing gear and brake systems, and other QD demanding installations . The Thread-Lok QD couplings can be used in a wide range of pressure and temperature applications while they provide a simple one-hand operation to thread the QD halves together with a visual confirmation of proper and full coupling to improve both time and safety. They incorporate a tang and slot design, with QDs engaging and locking in one position when the coupling halves are threaded together and fully connected, providing both visual and touch indication of the fully connected position. The QD can only engage with the tang and slot, to confirm full connection and full internal valve open flow position. The engaged slot and tang also provide a secondary locking in the connected position, preventing the coupling halves from unintentional uncoupling due to vibration in service.
Thread-Lok couplings use Parker’s efficient, self-sealing valve design that permits fluid flow with minimum pressure loss and turbulence. Flush-faced valve design also minimizes air inclusion or spillage during coupling or uncoupling. The design allows for simple, one-handed operation to connect (thread clockwise) or disconnect (pull back on the outer actuating sleeve and thread counter clockwise) the coupling halves during installation or maintenance on the fluid system. As the coupling halves are threaded together, the internal fluid flow path opens; when in the fully open position, the coupling halves are locked together using Parker Aerospace’s reliable and high-strength acme threads. The acme threads provide robust performance in harsh environments, along with making it impossible to cross thread during connection, as can be the case with finer thread products. Typical installations use the coupler half with latching mechanism on the hose or tube side, and the nipple half installed on a panel or in a manifold.The Thread-Lok quick disconnect requires linear movement to connect and disconnect along with room to access the outer, or actuating sleeve, by hand in order to pull back the sleeve and rotate to disconnect the two halves.
