GOODRIDGE QUICK DISCONNECT G-LINK PULL TYPE
PRODUCT CODE:

The Quick Disconnect Couplings of the Advantage series, G-Link Pull-Type, are compact and lightweight couplings, developed for hydraulic and pneumatic purposes in motorsport with operating pressure up to 200 bar. The locking mechanism is designed for one-hand opera- tion; no separate actuation of the retaining sleeve is required for operation. To verify the correct connection, the female half is equipped with a green indicator ring. This indicator ring can, alternatively, be replaced by a retaining clamp. This can only be attached when the halves are coupled and eliminates the risk of unintentional uncoupling. Additionally the whole operating mechanism is O-ring sealed to achieve particular suitability for rough conditions and to reduce environmental effects. Both halves, coupler and nipple, are equipped with self-acting valves to stop fluid loss during uncoupling, as well as air inclusion, during coupling.

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.
