Plumbing and heating fittings
Fittings and pipe should be kept clean and undamaged before use.
Sizes: 10mm to 28mm diameter.
Pipes: Speedfit fittings can be used with:
• Copper pipe to BS EN 1057
• Speedfit Barrier Pipe to BS7291
Speedfit fittings cannot be used on stainless steel pipe.
Standards: Speedfit products are designed and manufactured under a fully
integrated system assessed by B.S.I. to BS EN ISO9001 and are approved by
the Water Regulations Advisory Scheme. Speedfit ‘PEM’, ‘PSE’ and ‘SFM’
Fittings and Speedfit Barrier Pipe are Kitemarked to BS7291 Parts 1, 2 and 3
Class S (Licence No. KM39767).
Applications:
• Mains fed and indirect cold water systems
• Vented and unvented hot water systems
• Vented and sealed central heating systems
DO NOT USE FOR Gas, fuel oil or compressed air applications.

Burst Pressure (fittings): With copper or plastic pipe at 20°C: Speedfit
fittings used with copper or Speedfit Barrier Pipe will withstand pressures
well in excess of normal service conditions.
High Temperatures: Can withstand 114°C intermittently for short periods.
The Speedfit system should not be used on an uncontrolled heat source.
Insulation: Should comply with BS EN 806 and complimentary guidance
document BS 8558, and BS5422, as for copper.
Minimum Bend Radii (BPEX):

Min radium with clips 100mm 175mm 225mm 300mm
Min radius with cold forming bend 30mm 75mm 110mm -
Minimum Bend Radii (BPB):

Pipe diameter Clip spacing
Horizontal run Vertical run
10 - 15 300 500
22 500 800
28 800 1000
Where pipe is concealed, clipping may only be required where necessary.
Expansion (PEX pipe): 1% on length between 20°C and 82°C.
Flow Rates: Comparable with metal systems.
Cleaners, Inhibitors and Descalents: For advice on the replenishment of
additives such as corrosion inhibitors, the following manufacturers should
be contacted: Fernox Manufacturing Limited on 0330 100 7750, Sentinel
BetzDearborn Limited on 0151 424 5351 or Adey Innovations LLP on 01242
546717.
Paint and Chemicals: Use only water or oil based paint. DO NOT ALLOW
CONTACT WITH jointing compounds, cellulose based paints, paint thinners
or strippers, solder flux, acid based descalents or aggressive cleaning
products, including those below pH4, high in hypochlorite (e.g. bleach) or
containing hydrogen peroxide. (See the DISINFECTION OF HOT AND COLD
WATER SYSTEMS section of the Product Guide installation advice for
specifically permitted disinfection procedures).
Solder Flux: No fluxes of any types should come into contact with JG
Speedfit Pipe and Fittings. If fluxes are to be used in an environment where
Speedfit is installed, then (1) extreme care should be taken to ensure that
no such contact takes place and (2) JG recommend installers only use
fluxes tested and approved in writing in advance by JG. At the date of this
publication, the only such approved flux is Fernox Flux.
Chlorine: Speedfit is not suitable for use in systems where the water
contains high levels of chlorine. e.g. swimming pools, fountains etc.
Exposure to Sunlight: Speedfit products, when used indoors, are not
aected by sunlight. When used outdoors protect from ultra violet light by
lagging or painting.
Pipe Clips: Pipe clips should not be fitted any closer than 60mm from the
end of the fitting. Pipe should be adequately supported by pipe clips to
prevent undue stress (side load) on fittings.
Pipe Inserts: Must be used on all installations when using plastic pipe and
should be fully inserted. Only use a Speedfit Insert with Speedfit Pipe.
Metal Joists: When ‘cabling’ plastic pipe through metal joists ensure rubber
grommets are in place to prevent damage to pipe. Use of collet covers or
collet clips on fittings recommended.
Connection to Boilers: A minimum 1 metre run of copper pipe must be
installed between the boiler and the Speedfit system, as per BS5955:
Part 8.
Connection to Copper Pipe: 450mm is the minimum distance to make a
solder connection on copper pipe inserted into a Speedfit Fitting. Ensure
that any residual flux and solder does not come 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 to provide
accessibility for both pipe and fitting. As stated in Water Regulation
Schedule 2.7 and BS8000: Part 15, fittings and pipe should be removable
for possible replacement. Insulation is also recommended to protect
against heat loss and the eects of frost.
Electrical Continuity: If Speedfit is used in an existing metal system which
may have been used for earthing, electrical continuity should be reinstated.
Valves and Taps: Plastic 15mm and 22mm valves and taps available from
JG Speedfit Ltd are not suitable for central heating installations.
1/4 Turn Valves: These valves have been designed to allow temporary
servicing of downstream equipment and must only be used in the fully open
or fully closed position.
Do Not use these Valves:
• In a partially open position to control flow.
• To provide a permanent termination.
• Without tubing assembled or plugged (or threaded connections sealed).
• As a tap or “faucet”.
