CPVC Pipes conforming to ASTM Standards.
Speedfit
®
fittings cannot be used on stainless steel pipe.
• Standards: Speedfit
®
products are designed and manu-
factured under a fully integrated system assessed by B.S.I.
to BS EN ISO9001. Speedfit
®
PEI and PSEI Fittings and
Speedfit
®
PEX Pipe are also NSF-14 and NSF-61, IAPMO
and ICC listed.
• Do not use for gas, fuel oil or compressed air applications.

Water 80 psi 200° F
• Burst Pressure (fittings): Speedfit
®
fittings used with copper,
CPVC or Speedfit
®
PEX Pipe will withstand pressures well in
excess of normal service conditions.
• Insulation: Comply with code requirements.
• Minimum bend radius (PEX):
Pipe Diameter 1/2" CTS 3/4" CTS
Min radius 7" 9"
• Clip spacing (in inches):
For surface mounted pipes.
Clip Spacing
Pipe Diameter Horizontal Run Vertical Run
1/2" CTS 16” 20”
3/4" CTS 20” 30”
1" CTS 30” 36”
• Expansion (PEX Pipe): 1% on length between 68°F and
180°F.
• Flow rates: Comparable with metal systems.
• Cleaners, inhibitors and descalents: For advice on the
use of additives such as corrosion inhibitors, the additive
manufacturers should be consulted.
• Paint and Chemicals: Only use water or oil based paint. DO
NOT ALLOW CONTACT WITH cellulose based paints, paint
thinners or strippers, solder flux or acid based descalents or
aggressive household cleaning products.
DO NOT ALLOW CONTACT WITH jointing compounds,
cellulose-based paints, paint thinners, paint strippers, solder
flux, acid-based descalents or aggressive cleaning products.
• Solder Flux: No fluxes of any type should come into contact
with Speedfit
®
products. Extreme care should be taken to
ensure that no such contact takes place.
• Chlorine: Speedfit
®
is suitable for use with water supplies
containing up to 4ppm of chlorine.
• Exposure to light: Speedfit
®
products, when used indoors,
are not affected by sunlight. When used outdoors, protect
from ultraviolet light by lagging or painting.
• Pipe clips: Pipe clips should not be fitted any closer than 2.5
inches from the end of the fitting. Pipe should be adequately
supported by pipe clips to prevent undue stress (side load) on
fittings.
• Pipe inserts: Plumbing: John Guest recommends the use
of pipe inserts for PEX pipe connections with John Guest
Speedfit
®
products in Standard Residential Plumbing (hot and
cold water) installations.
Pipe inserts: Heating: John Guest requires the use of pipe
inserts for PEX pipe connections with John Guest Speedfit
®
products in all Heating installations.
• Metal joists: When ‘cabling’ plastic pipe through metal joists,
ensure rubber grommets are in place to prevent damage to
the pipe.
• Connection to boilers: A minimum 36 inches run of copper
pipe must be installed between the hot water heater and the
Speedfit
®
system.
• Connection to Hot Water Heater: A minimum 18 inches
run of copper pipe must be installed between the hot water
heater and the Speedfit
®
System.
• Connection to copper pipe: 18 inches is the minimum
distance to make a solder connection on copper pipe inserted
into a Speedfit
®
fitting. Ensure that no solder flux comes into
contact with the fitting.
• Concrete and masonry: Speedfit
®
pipe and fittings can be
laid in concrete and masonry providing they are installed in
conduit pipe with access boxes for the fittings. This is to
enable the pipe to expand and provide accessibility for both
pipe and fittings. Fittings and pipe should be removable for
possible replacement. Insulation is also recommended to
protect against heat loss and the effects of frost. Fittings not
to be used underground.
• Electrical continuity: If Speedfit
®
is used in an existing metal
system, electrical continuity must be reinstated.
• System testing: To ensure the pipework and fittings have
been installed correctly, whether it be on a new or extended
system, it is essential that the system be checked and
hydraulically wet tested. Testing should be at 30 psi for 10
minutes and 150 psi for 10 minutes. This testing, combined
with other relevant checks, should reveal installation problems
and is regarded as good plumbing practice. However, system
testing should not be regarded as a substitute for correct
installation (see also “Making a Good Connection”).
• Disinfection of Hot and Cold Water Systems. Speedfit
®
can be disinfected after installation or as part of a routine
maintenance program. The disinfection procedure must
comply with code requirements. Only disinfection solutions
specifically recommended as suitable for contact with plastic
plumbing systems and, where necessary, employing specialist
contractors may be used with Speedfit
®
.
Disinfection solutions must only come into contact with
the internal (wet) surfaces of the system. If any normal
dry surfaces of a Speedfit
®
fitting come into contact with
disinfection solution the whole fitting must be replaced
immediately. The disinfection solution must be immediately
flushed out at all draw out points with fresh, clean water at
the end of the disinfection period. The solution must not be
left in the system.
• System flushing: As is usual practice for any plumbing
installation, flushing of the system prior to the use of Speedfit
®
is recommended to remove any contaminants/chemical
residue from elsewhere in the system.
• Vermin: Speedfit
®
products will need special protection in
vermin infested areas.
• Tube insertion depths:
1/2” CTS 3/4” CTS 1” CTS
Twist and Lock Fittings 1 1/4” 1 5/8” 1 5/8”
Test Caps 1 1/8” 1 1/2” 1 1/2”
Brass Fittings 1 1/8” 1 1/2” 1 1/2”
• Side Loads: Fittings should not be subject to excessive
side loads and they should not be used as support brackets.
Tubing should be adequately supported to prevent excessive
side loading.
• Maximum torque values of threads: in Ft Ilbs
1/2” NPT 3/4” NPT 1” NPT
Plastic NPT 2 3 3
Metal NPT 3 4 4
It is recommended that all installations are checked prior to
use to determine that a seal has been made.
