Apollo Valves UN114 Press Union 1-1/4 in Pxp Low Lead Brass

Product Description

The APOLLO VALVES UN114 is a small-diameter press union designed for copper-to-copper (PxP) connections in pressurized plumbing and hydronic systems. The body is constructed from lead-free, dezincification-resistant brass, making it suitable for potable water and mechanical piping applications. An EPDM o-ring provides the sealing element at each press end. Manufactured to ASTM material and dimensional standards, this union is a reliable choice for licensed plumbers and pipefitters working on residential and light commercial systems where soldering is impractical or code-restricted.

The UN114 is intended for 1-1/4-inch press-fit copper tubing connections in closed-loop hydronic heating, domestic hot and cold water distribution, and similar fluid-handling systems. The press connection method eliminates open flame, reducing fire risk in confined or combustible spaces. The Leak Before Press feature alerts installers to any unpressed joint before the system is fully pressurized, providing a built-in quality check during commissioning.

Key Features

• Lead-free, dezincification-resistant brass body meets low-lead requirements for potable water service
• EPDM o-ring seal rated for use in water and hydronic fluid applications
• Press x Press (PxP) end connections for flame-free installation
• Leak Before Press technology identifies unpressed joints during system pressure testing
• Manufactured to ASTM material and fabrication standards

Compatibility

Designed as an OEM-style press union for 1-1/4-inch copper press-fit piping systems using standard press tooling compatible with the ApolloPress 8733 series small-diameter press fittings.

Installation Notes

Installation requires a calibrated press tool equipped with the correct jaw size for 1-1/4-inch press fittings. Shut off and depressurize the system and drain standing water before fitting installation. Inspect each press end for proper o-ring seating and tube insertion depth before pressing. Follow all applicable IPC and local plumbing code requirements for press-fit copper fittings in the jurisdiction of installation.
