Resideo HS-PRESS-103 Press Kit

The Resideo HS-PRESS-103 Press Kit is a heavy-duty 1-1/4 inch union press adapter designed to streamline the connection between your hydraulic separator and the rest of the hydronic system. Built from high-grade brass, this kit includes two union fittings specifically engineered for use with the HYDROSEP-103-U union separator. For contractors running high-efficiency boiler loops, these specialized press fittings for hydraulic separators eliminate the need for traditional soldering or threading, significantly reducing man-hours on the job site while maintaining a leak-proof seal under rigorous operating conditions.

This HVAC press connection kit supports critical flow management by ensuring a seamless transition for 1-1/4" piping. The fittings are rated for a maximum working pressure of 145 PSI (10 Bar) and can handle fluid temperatures ranging from 32°F to 230°F. When installing a magnetic hydraulic separator, utilizing this 1.25 inch press adapter set provides the build-your-own flexibility required for modern residential and light commercial hydronic configurations. Note that two union kits are typically required per valve installation to complete the primary and secondary circuit connections.

• Compatible with HYDROSEP-103-U magnetic hydraulic separators for rapid system integration.
• Constructed from durable brass to resist corrosion and handle high-temperature hydronic fluids.
• Features a flame-free press connection that eliminates the risks and time associated with brazing or soldering.
• Designed for versatility in both residential boiler piping and commercial HVAC applications.
• Ensures a secure, professional-grade seal that meets DN32 connection size specifications.

Is this kit compatible with other hydraulic separator brands?
This kit is specifically engineered as an adapter for Resideo HYDROSEP units. While the 1-1/4" press side follows industry standards, the union side is matched to Resideo’s proprietary hydraulic separator housing to ensure a proper fit and seal.

How many fittings are included in the HS-PRESS-103?
Each HS-PRESS-103 kit contains two individual union press adapters. Since most hydraulic separators require four total connections, you will typically need to purchase two kits for a complete installation.

Can I use these fittings with glycol-based hydronic systems?
Yes, these brass adapters are compatible with water and glycol-based solutions (up to a 50% concentration), making them suitable for most standard heating and cooling loops.
