Highlights of the New Fittings

• Shortened thread portion of the fittings to better suit CPU and GPU block depths—this improves flow.
• No unneeded wrench flats.
• O-ring shoulder made with appropriate thickness—as in thinner. Makes for a shorter fitting overall without sacrificing needed length in the barrel portion.
• O-ring shoulder disappears when installed in current and future PrimoChill products, or any other quality brands that have O-ring retention built in.
• Tool Free Design, simple and easy installation.
• Made from Ultra Strong Polycarbonate with a Proprietary UV-Resistant resin for bullet proof quality that lasts.
• Smallest 1/2in. x 3/4in. Compression Fitting available.
• Lightest 1/2in. x 3/4in. Compression Fitting available, no need to add extra weight to your expensive CPU/Motherboard.
• Keeps heat in the fluid (where it belongs)--unlike metal fittings that can dissipate heat into your case and not your radiator.
• Perfectly matched to PrimoFlex Pro LRT Tubing colors. 
• Paintable -- painting is easy and the result is exceptional. When the carpet needs to match the drapes in your mod, reach for PrimoChill Poly Ghost fittings.

PLEASE NOTE: It is important for the integrity of the compression fitting that excessive force is avoided in tightening the ring. If the ring is overtightened, the tube will become deformed, lose contact surface and cause leaks. Over-tightening is the most common cause of leaks in all compression fittings. As a general rule, the compression ring should be "finger tight" and then tightened one-half more of a turn with your fingers. All fittings should then be "leak" tested, and if slight weeping is observed, the fitting should be slowly tightened a bit more until the weeping stops.
