Recessed pendent sprinklers
Recessed pendent sprinklers thread onto Uponor's fire sprinkler adapter fittings. Sprinklers are NSF- and UL-approved for combined plumbing and fire sprinkler systems. Note: Protective plastic caps, escutcheons and tension collars sold separately. Do not store sprinklers where the ambient temperature will exceed 100°F. Sprinkler wrench required to assemble sprinkler and adapter.
Repair couplings
Use 5/16" repair couplings for 5/16" PEX x 5/16" PEX.Note: One-piece repair coupling comes as an assembly. No other fittings are necessary. For all other sizes of tubing, see ProPEX EP couplings section on pages 98-99. EP couplings are suitable for direct burial.
Threaded brass manifold straight adapters and bushings
Threaded brass manifold straight adapters and bushings transition the R32 manifold union nut to PEX or MLC tubing with QS-style fittings.
TruFLOW classic manifold elbow unions
TruFLOW Classic manifold elbow unions feature an R32 union by 11⁄4" BSP male connection. They are designed to make tight, 90-degree turns from the TruFLOW Classic manifold supply and return connections. Use silicone lubricant on the male threads to ease installation.
TruFLOW manifold coupling nipples
TruFLOW manifold coupling nipples feature male BSP thread on both ends and are used to make the connection between manifold parts. Primary seal for the connection is made with the attached O-ring on the nipple. Thread sealant on the nipple ensures tight bonding between the nipple and the manifold. Use silicone lubricant on the male threads to ease installation.
TruFLOW manifold loop temperature gauges
TruFLOW manifold loop temperature gauges come with a QS20 female union on one end and a QS20 male on the other. Temperature gauge with well and removable temperature gauge are included.
TruFLOW visual flow meters
Use TruFLOW visual flow meters on TruFLOW Jr. and TruFLOW Classic manifolds to accurately measure the flow of hydronic radiant loops.Note: For proper operation, install flow meters on the return manifold.
EP heating manifold elbows
EP heating manifold elbows enable connections to supply and return piping from above or below. The two elbows feature different lengths to accommodate tube spacing for the supply and return lines.
ProPEX engineered polymer (EP) water meter fittings
Targeted for commercial multifamily sub-metering as well as residential whole-home metering, Uponor's ProPEX water service offering is designed for direct connection to water meters sized 5⁄8" to 1".ProPEX EP water meter fittings provide a straight or 90-degree connection to water meters for 3⁄4" and 1" Uponor AquaPEX tubing. They are sold as a kit containing the fitting along with a gasket and two swivel nuts (EP nuts for plastic meters and metal nuts for metal meters).
ProPEX EP 45 elbows
ProPEX EP elbows make 45-degree connections for Uponor PEX tubing in supply and return mains. Note: ProPEX tool is required. ProPEX rings sold separately.
ProPEX EP 90 elbows
ProPEX EP elbows make tight, 90-degree connections for Uponor PEX tubing in supply and return mains. Note: ProPEX tool is required. ProPEX rings sold separately.
