Components for today’s modern hydronic systems

 Presscon

™

copper connections makes

installation of Calefﬁ components fast,

easy and efﬁ cient using standard press

compression tools.

 Special slots in EPDM O-ring allows ﬂ uid to

leak during system testing if unpressed and

the perfect leak proof seal when completely

pressed.

 Press sizes from ½" to 2" copper are available

on several air separators, dirt separators,

hydronic separators, magnetic separators,

thermostatic mixing valves, balancing valves,

press reducing valves, zone valves and more.

 Temperature range of 0°F—250°F with pressure

rating to 200 psi and up to 50% glycol mixture

Fittings meet low lead law requirements for use

in accordance with U.S. and Canadian plumbing

and mechanical codes.
