Connection to
compression fitting
Many but not all compression fittings are suitable for
use with plastic fittings and pipe. Users should therefore
check for compatibility. Compression fittings with short
tube stop depth or brass olives should not be used
with plastic fittings or pipe.
When using compression fittings with Speedfit pipe,
a Standard Pipe Insert (prefix TSM) must be used to
withstand the compressive pressure of the olive.
The olive must be located within the length of the
pipe insert and the pipe fully inserted into the fitting.
The connection should not need more than 2 full
turns after the olive has gripped the pipe. JG Speedfit
recommends the use of soft copper olives.
Ensure nut and olive are in place before
inserting pipe insert.
Connection to imperial
pipe and fittings
The Speedfit Range includes couplers to connect
Speedfit Pipe to 1/2" to 1" BSP and BSPT.
Connection to
chrome-plated copper pipe
Speedfit fittings can be connected onto chromium plated
copper pipe if the chromium plating is completely
removed to the full depth of the fitting. To ensure
maximum grip we recommend fitting a collet clip.
It is not possible to connect Speedfit fittings to
stainless steel pipe.
Connection to mains supply
In modern properties, water enters a building usually in
blue MDPE (medium density polyethylene) pipe. In order
to comply with Water Regulation Schedule 2.10, the
internal plumbing system should be connected via a
Speedfit Stop Tap from our Cold Water Services Range,
Part No.’s UGSTV2515, 25mm x 15mm or UGSTV2522,
25mm x 22mm.
Connection of Speedfit pipe to supply pipe of other
materials should be via a stop tap with a 15mm or 22mm
compression outlet.
