ProPEX Fittings
Uponor offers a comprehensive line of
engineered plastic (EP), lead-free brass (LF),
red brass, standard yellow brass and WIPEX
DZR brass fittings to effectively meet any
residential or commercial plumbing or
radiant application.
Engineered Plastic (EP)
Uponor’s engineered plastic (EP) is a high-
performance thermoplastic material that has
superior mechanical, chemical and thermal
properties, which allow dimensional stability
in demanding applications, including areas
of high stress, heat and moisture. Uponor EP
fittings are approved for direct burial in soil
as well as concrete slabs. EP fittings carry the
same ratings as Uponor tubing.
Lead-free Brass (LF)
Our lead-free brass offering carries the NSF
us-pw-G marking for lead-free compliance to
meet state lead-level legislation and exceed
the U.S. Safe Drinking Water Act. Combine
these fittings with Uponor’s PEX-a tubing, EP
offering and ProPEX Out-of-the-Wall for the
industry’s first complete lead-free plumbing
system from inlet to faucet. Uponor’s lead-free
brass is approved for direct burial in soil as well
as concrete slabs.
Red Brass
Our red brass fittings feature less than 15%
zinc, which provides enhanced resistance to
dezincification. Red brass fittings are also
safe for direct burial in soil in accordance with
Uponor installation guidelines.
Brass
Uponor’s yellow (also called 360) brass
products offer all the benefits professionals
have come to expect from a standard brass
plumbing and radiant product. Uponor’s yellow
brass offering features ProPEX connections for
a solid, leak-resistant union without the need
for torches, glues, solvents or gauges.
WIPEX Dezincification-resistant
(DZR) Brass
Available in sizes 1" to 4", Uponor’s WIPEX
fittings are made from a dezincification-
resistant brass that offers added resilience
in direct-burial applications. WIPEX fittings
require the use of a chamfering tool, WIPEX
Sleeve Pliers and a wrench to make strong,
durable connections in a matter of minutes.
* Per NSF Annex G, lead-free products contain no more
than 0.25% weighted average lead content on
wetted surfaces.
