CANPEX™ ULTRA Multi-layer Cross-linked Polyethylene (PEX)
with Tracer Wire
SCOPE: This material specification designates the requirements for CANPEX ULTRA hot and cold
water distribution tubing with Tracer Wire for the use of Water Service lines. All CANPEX ULTRA tubing is
copper tube size dimension (CTS), SDR-9 wall thickness and meets the requirements of ASTM F876 and
F877. All the Tracer Wire conforms to the Ontario Building Code section 7.2.11.3.
MATERIALS: All CANPEX ULTRA tubing is manufactured from a cross-linkable high density polyethylene
produced by grafting organo-silanes onto a polyethylene base. A catalyst (accelerator) added to the crosslinkable polyethylene during extrusion initiates the cross-linking process. Cross-linking is completed with
hot water or steam (sauna). The multi-layered construction ensures the customer that if the pipe is exposed
to UV light, its physical properties as well as its long term Chlorine/ORP resistance will be retained at
the highest level in the industry today. The exterior layer, also with superior Chlorine/ORP resistance, is
provided in blue for easy identification. All Tracer Wire is 14 gauge TW solid copper light colored plastic
coated tracer wire.
MARKING & CERTIFICATION: All CANPEX ULTRA tubing is marked with the name VPFL as the manufacturer,
nominal size, plastic tubing material designation code PEX 5306 (indicating that the PEX tubing has been tested and
TechData
meets the F876 requirements for minimum chlorine resistance at the end use condition of 100% @140˚F), design
pressure and temperature ratings, relevant ASTM standards, manufacturing date and production code, as well as
NSF-pw stamps (indicating third-party certification by NSF International for meeting and exceeding performance
and toxicological standards, as well as achieving the highest chlorine resistance rating in the PEX industry).
NSF conducts random on site inspections of the manufacturing facilities and independently tests CANPEX
ULTRA tubing for compliance with physical, performance, and toxicological standards. CANPEX ULTRA is
also certified to meet the Uniform Plumbing Code, NSF 14/61, NSF Annex G (Lead Free), CSA (Canadian
Standards Association) B137.5 (cNSF), ULC/UL (Underwriters Laboratory) S101/UL263 and ULC S102/E84
through Warnock Hersey.

RECOMMENDED USES: CANPEX ULTRA tubing is intended and recommended for use in hot and cold potable
water distribution systems. Design temperature and pressure ratings for CANPEX ULTRA are 160 psi @
73˚F and 100 psi @ 180˚F. CANPEX ULTRA tubing can be used in “continuously recirculating hot water
plumbing systems” at temperatures of up to 140˚F while still maintaining excellent chlorine resistance.
With the Tracer Wire and the CSA B137.5 CANPEX ULTRA tubing meets all the Ontario Building Code
specifications for Water Service Tubing (OBC Trace Wire specification 7.2.11.3). In Ontario when used for Water
Service Tubing there is no need for a check valve (as per OBC section 7.6.1.10). For information on the suitability
for other hot and cold water applications not listed here, consult with your CB Supplies representative.
HANDLING AND INSTALLATION:
CANPEX ULTRA cross-linked polyethylene tubing is tough yet flexible. However, it is softer than metals and
may be damaged by abrasion or by objects with cutting edges. Use of these materials in hot and cold water
distribution systems must be in accordance with good plumbing practices, applicable code requirements
and current installation practices available from CB Supplies. CANPEX ULTRA is manufactured to meet
written National standards. Contact a CB Supplies representative or the applicable code enforcement bureau
for information about approvals for specific applications.

QUALITY ASSURANCE
When the product is marked with ASTM F876/
F877 and CSA B137.5 designations, it affirms
that the product was manufactured, inspected,
sampled and tested in accordance with these
specifications and it has been found to meet the
specified requirements.
CERTIFICATIONS
Indicates that the tubing has been tested and
meets the F876 requirements for minimum
chlorine resistance at the end use of condition
of 100% 140˚F (60˚C) (old domestic re-circulation
rating, CL-R). NSF tested according to ASTM
Standard F2023, evaluating the oxidative
resistance of Cross-linked Polyethylene (PEX)
tubing and systems to hot chlorinated water
greatly exceeding the minimum chlorine
resistance requirements of ASTM F876.
