Apollo PEX Coupling Jar

The Apollo APXC3425JR is a 25 pack of 3/4 inch brass PEX barb couplings supplied in a jar. These fittings form part of the ApolloPEX system for potable water and hydronic heating installations. They are designed for use with copper crimps, stainless steel pinch clamps or stainless steel crimp sleeves, which are sold separately. The product is new and ships directly from the manufacturer.

Suits installers needing multiple couplings

This pack suits plumbers and RV owners who need a quantity of straight couplings for a complete piping job. It is not for buyers who only need a single fitting or who require elbows, tees or valves that are not included in this jar. The fittings are specific to PEX tubing and will not work with copper, CPVC or other pipe materials without appropriate transition components.

Brass construction handles sustained pressure

Under continuous system pressure the brass body resists deformation and maintains seal integrity across temperature cycles typical of hydronic heating. The barb design grips the tubing evenly when secured with an approved clamp or crimp method, preventing leaks during prolonged operation. California Proposition 65 warnings apply because the product contains a chemical known to the state to cause cancer and reproductive harm.

Questions about this item

What size PEX tubing does the 3/4 in. ApolloPEX coupling connect?

The coupling joins two lengths of 3/4 in. PEX tubing using a barb-to-barb design.

Which separate fasteners are compatible with the brass coupling for a secure joint?

Copper crimp rings, stainless steel pinch clamps or stainless steel crimp sleeves (all sold separately) can be used to secure the coupling.

How can I verify the joint is watertight after installing the coupling and fasteners?

Pressurise the system and inspect each connection for leaks; a dry joint confirms the crimp or clamp was applied correctly.
