3/8" PEX-to-EP manifold connector pair
This pair of Legend Valve 810-142EP connectors joins 3/8-inch PEX tubing to an M-8100 manifold. They are intended for installers and maintenance technicians working on hydronic heating or potable-water distribution systems. The fittings arrive new and comply with the manufacturer's stated specifications for this connection type.
California Proposition 65 warnings apply
The supplier notes that the product contains a chemical known to the State of California to cause cancer and a chemical known to cause birth defects or other reproductive harm. These regulatory warnings do not alter the mechanical function of the connectors but must be acknowledged during specification and handling.
Straightforward press or crimp installation
Installation follows standard PEX-to-manifold procedures using compatible press or crimp tools for 3/8-inch tubing. The most common issue is an incomplete seat or an undersized crimp ring, which can lead to leaks at the manifold port. Verifying full insertion and correct tool calibration before pressurising the system avoids callbacks.

Questions about this item
How often should the 3/8" PEX-to-EP connectors be inspected or replaced?
Inspect the connectors annually for leaks or corrosion; replace them if any degradation is found during routine system maintenance.
What pressure or temperature limit is reached first during continuous heating cycles?
The connectors are rated for the M-8100 manifold's design limits; the system pressure relief valve typically activates before the fittings reach their maximum.
Does the manifold heat up or draw extra power when the heating runs all day?
The brass connectors conduct heat from the circulating fluid but add no electrical load; surface temperature follows the water temperature supplied by the boiler.
