Apollo

Apollo ExpansionPEX 3/4 in. Brass Barb x Male Pipe Thread Ball Valve

SKU CH-88Z5-S27GV

A brass quarter-turn ball valve connects 3/4 in. PEX-A tubing to male pipe threads for potable water or hydronic systems

  • Quarter-turn lever handle gives smooth flow control
  • Brass body resists corrosion in potable water systems
  • ExpansionPEX design enables direct transition to PEX-A piping
  • Lead-free construction meets Proposition 65 standards
  • Cold-expansion tool required for secure sleeve connection

Transition Valve for PEX-A Systems

This Apollo ExpansionPEX ball valve connects 3/4 in. male pipe threads to PEX-A tubing, enabling a direct transition between dissimilar piping types. The lead-free brass body suits potable water lines and hydronic heating loops alike. A quarter-turn lever handle delivers anti-stick, smooth flow control. It is intended for installers adapting existing infrastructure to ExpansionPEX networks.

Installation Requirements and System Integration

A cold-expansion tool and compatible expansion sleeves or rings are required to secure the barb connection; both are sold separately. The valve becomes a functional component within the broader Apollo ExpansionPEX ecosystem of fittings, manifolds, fasteners and tubing. No additional adapters are needed for the 3/4 in. male thread side. This design frees the installer from sourcing separate transition couplings and threaded valves.

Sustained Service Behaviour

The lead-free brass construction resists dezincification and corrosion during continuous contact with potable water or heating fluid. The quarter-turn mechanism maintains reliable shut-off without seizing after prolonged static periods. California Proposition 65 warnings apply because the product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. The valve is new and ships directly from the manufacturer.

Questions about this item

What size cold-expansion tool is needed for the 3/4 in. barb connection?

A 3/4 in. cold-expansion tool is required to expand the PEX-A tubing before inserting it onto the barb; the tool is sold separately.

Does the brass body or lever handle become hot during continuous hot-water circulation?

The valve body and handle will reach the temperature of the circulating water, so insulation or a handle cover is recommended for sustained high-temperature hydronic use.

Which separate sleeve or ring must I already own to secure the PEX-A tubing to this valve?

You need an Apollo ExpansionPEX sleeve or a comparable expansion-type ring that matches the 3/4 in. tubing size; both are sold separately.
