The CUSTOM MOLDED PRODUCTS 23442-000-100 is a spa jet body from the Typhoon 400 Series, designed as the structural housing for 4-inch Typhoon jets in residential and commercial spa installations. The unit features a 3/8-inch ribbed barb air port and a 3/4-inch ribbed barb water port, providing secure hose connections without the need for clamps. It ships complete with a mounting nut and gasket, giving service technicians the hardware needed for a full replacement in a single part. Pool and spa technicians install this component during jet rebuilds, shell repairs, or system upgrades where the existing jet body is cracked or no longer seals correctly.
This jet body is specifically compatible with the 400 Series Typhoon 4-inch jet system. Hole sizing at the spa shell varies by gasket type: a flat gasket requires a 2-5/8-inch hole, while an L-gasket installation requires a 2-3/4-inch hole. Both dimensions apply to standard spa shell materials. The barbed water port configuration suits installations using flexible spa plumbing. A slip water connection variant of this jet body is also available for installations requiring solvent-weld fittings. Replacement gaskets are available separately under part number 23442-000-050.
Designed for use with 400 Series Typhoon 4-inch spa jets. Accepts flat gasket with a 2-5/8-inch shell hole or L-gasket with a 2-3/4-inch shell hole. A slip water connection version of this jet body is also available for alternate plumbing configurations.
Installation is performed by licensed pool and spa technicians. Shut off the spa pump and depressurize the plumbing circuit before removing the existing jet body. Verify the shell hole diameter matches the gasket type being used before securing the mounting nut. Do not overtighten the mounting nut against the spa shell, as cracking the shell surface or gasket seat will require additional repair.
