    This kit converts a radiator or water pump inlet or outlet neck to an -AN connection without welding. A clamp and O-ring go on first, then the fitting is tightened down for additional compression, giving a firm bolt on connection that CVF rates for at least 120 PSI.

    It can also replace hose clamps on a water pump inlet. The kit is offered with a -16AN or -20AN fitting, in four clamp sizes to match the neck diameter, and in Polished, Stealth Black or C3 Ceramic Clear Coat. CVF lists the design as patent pending.

    FAQ

    Does the RAD-AN-KIT require welding?

    No. It clamps onto the existing radiator or water pump neck and uses compression to seal, so no welding is needed.

    What pressure is it rated for?

    CVF rates the connection for at least 120 PSI.

    Which -AN sizes are offered?

    The kit is offered with either a -16AN or a -20AN fitting.

    How do I pick the clamp size?

    Choose the clamp that matches the neck: 1.25 in. for 1.2 to 1.35 in., 1.5 in. for 1.45 to 1.6 in., 1.85 in. for 1.7 to 1.85 in., or 2.0 in. for 1.85 to 2.0 in.

    What is in the kit?

    A clamp with hardware, the -AN fitting, a compression ring and an O-ring.
