G-Link Fitting

• 3/8-24 thread 

The Quick Disconnect Couplings of the Advantage series, G-Link Bayonet-Type are compact and lightweight couplings, developed for hydraulic and pneumatic purposes in motorsport with operating pressure up to 200 bar. The locking mechanism with bayonet is designed for one-hand operation, pushing and twisting the outer sleeve, with no separate actuation required for operation. Both halves, coupler and nipple, are equipped with self-acting valves to stop fluid loss during uncoupling, as well as air inclusion during coupling.

Optionally the dry break coupling can be used as a security shut-off device, e.g. for fuel lines. For this purpose one half of the coupling is equipped with a lanyard to separate the halves in case of an accident. The unique locking mechanism design allows activation of separation by pulling the male half. So it is possible to install two inversely arranged couplings to avoid the risk of mistakes. All body sizes of the G-Link Pull- Type series Quick Disconnect Couplings are also available in
a non-locking version, designed for the use in refill units. Please ask for additional information on couplings and refill units.

Technical Information:

FKM (Viton) seals, in use in fuel systems for many years, don’t have the chemical resistance for usage with current fuel mixtures, where ethanol or methanol are incorporated. Goodridge found the perfect solution for this challenge: a compound also resistant to all currently used fuel blends, e.g.

• Adblue (additive for scr; selective catalytic reduction)
• B5 (Diesel Blend; Containing 5% Biodiesel)
• B10
• B20 (Biodiesel)
• B100 (Biodiesel)
• E85 (gasoline blend; containing 85% Ethanol)
• Vegetable Oil
• Ethanol

Additionally this applied compound has at least the same resistance to temperature and mechanical stress as the standard FKM compound and is even better qualified for lower temperatures than FFKM compounds e.g. Kalrez. The consequence for motorsport applications is that the complete range can be covered with only two different sealing materials.

The standard sealing material is a modified fluorinated rubber compound (FPM, FKM, Viton), which is identified with the suffix “B”. This new material is only available in G-Link Quick Disconnect Couplings and allows the use for fuel-alcohol mixtures, pure ethanol and vegetable oil. Other materials as nitrile rubber (NBR), Tetraflouroethleyne + Propylene (TFE/P) are available on request.
