Manufactured using an Uponor-proprietary technology, Uponor helioPEX™ X2 is an oxygen-barrier PEX pipe that conforms to DIN 4726 and is designed as a competitive alternative for residential radiant heating applications. The pipe features exceptional workability, flexibility, and kink repairability and is backed by a 25-year limited warranty. Uponor helioPEX X2 is rated and listed by the Hydrostatic Stress Board of PPI at 93.3°C (200°F) at 80 psi, 82.2°C (180°F) at 100 psi, and 23°C (73.4°F) at 160 psi. The product offering is available in ½", ⅝", or ¾" coils and is compatible with ProPEX® ASTM F1960 expansion, ASTM F2080 compression, and ASTM F1807 crimp fittings.

Note: Uponor helioPEX X2 is not approved for potable-water applications.

All pre-insulated pipe systems insulation kits make insulated connections of single or twin-style Ecoflex pre-insulated pipe with a jacket size of 5.5", 6.9" and 7.9". The kits feature two shells, stainless-steel bolts, plastic pins and joint-sealing compound.Note: Uponor ProPEX fittings and EPDM rubber end caps are required at all ends of the piping system to ensure system integrity.H-insulation kit allows for several options of insulated connections between four or five branches of single and twin-style Ecoflex pre-insulated pipe.

Horizontal sidewall sprinklers thread onto Uponor's fire sprinkler adapter fittings. Sprinklers are NSF- and UL-approved for combined plumbing and fire sprinkler systems. Sprinklers designated LF are also NSF Annex G compliant. Note: Protective plastic caps, escutcheons and covers sold separately. Do not store sprinkler assemblies where the ambient temperature will exceed 100°F. Recessed sprinkler wrench required to assemble sprinkler and adapter.

For point-of-use shutoff at the fixture, compression straight and angle stop valves are lead-free (LF) brass, chrome-plated, quarter-turn ball valves that include a stainless-steel insert for compression connection to 1/2" Uponor AquaPEX® pipe and a 3/8" male threaded connection for fixture risers. For rigid fixture riser connections, use the Uponor ⅜" OD Compression Nut and Nylon Sleeve (part number F5440380), sold separately.

Metal bend supports (zinc-plated) provide a rigid, 90-degree bend for 3/8", 1/2", 5/8" and 3/4" Uponor PEX tubing.

Metal drop ear bend supports (zinc-plated) provide a rigid, 90-degree bend and connection-free stub out from a stud wall or floor for 3/8" or 1/2" Uponor PEX tubing.

Metal straight-through supports (zinc-plated) provide rigid straight-through support for 1/2" Uponor PEX tubing as it exits a floor.

PEX-a pipe supports are made of 23-gauge, galvanized steel and are available in 1/2" to 3-1/2" sizes for suspended commercial plumbing and hydronic piping applications, enabling extended support spacing. Each package quantity contains 15 support straps (i.e., three support straps per 9-ft. length).

PEX clips provide excellent holding power. The 3/8" and 1/2" can attach together laterally for tight installations. PEX clips attach under the wood subfloor for joist-heating applications. The clips prevent the tubing from coming in direct contact with the subfloor, eliminating the possibility of creating uncomfortable hot spots on the floor above. Drywall screws are commonly used to secure the clips to the wood subfloor.Note: Select a screw length that does not penetrate entirely through the wood subfloor once installed.
