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 transition the R32 manifold union nut to PEX or MLC tubing with QS-style fittings.
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 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.
