Apollo PEX 3/4 in. Copper Crimp Rings

The Apollo PEX 3/4 in. Copper Crimp Ring Jar supplies 100 copper rings for securing PEX tubing to barb fittings in potable water and hydronic heating systems. The rings are made from copper for durability and are designed for use with brass or plastic fittings, valves and manifolds. A crimping tool is required and sold separately. This pack suits plumbers and installers building or repairing PEX piping networks.

Installation thermals noise and power

These copper crimp rings are passive components that generate no heat, noise or electrical draw during normal use. They create a mechanical seal when compressed with a crimping tool and remain inert within the piping system. No power supply, ventilation or acoustic consideration is needed for the rings themselves. Performance depends on correct tool calibration and fitting compatibility.

Build quality and daily implications

Each ring is manufactured from copper to resist corrosion in potable water and heating applications. The 100-count jar keeps rings organised and protected on site or in the workshop. Compatibility with both brass and plastic fittings allows flexibility across mixed-material installations. California Proposition 65 warnings apply because the product contains a chemical known to the state to cause cancer and birth defects or other reproductive harm.

Questions about this item

How do I install the 3/4 in. copper crimp rings from the 100-pack jar?

Slide the ring over the PEX pipe, insert a brass or poly alloy barb fitting, then compress the ring with a calibrated crimping tool sold separately; the step most people miss is verifying the crimp gauge reading before pressurising the system.

What maintenance or replacement will these copper crimp rings need later?

The rings themselves are permanent once crimped; inspect them during any system service for corrosion or deformation, and replace only if a fitting is removed — otherwise no scheduled maintenance is required.

What limit shows up first under sustained pressure and temperature cycles?

The copper ring can work-harden and lose elasticity over repeated thermal expansion, so the first limit is typically a leak path forming at the crimp joint if the system exceeds design pressure or temperature ratings.
