Fitting with self-adjusting diameter for simple and multi-layer plastic pipes series 680
Function
The self-adjusting fitting for simple and multi-layer plastic pipes is a mechanical device that allows the pipes, the radiant
panel system circuits and the manifolds to be connected easily and securely. This versatile fitting has been specifically
designed to adapt to the varying pipe diameters of these types of systems.

Construction details
Versatility of pipe-fitting
This fitting has been specifically designed to adapt to several pipe diameters. The large variety of simple
and multi-layer plastic pipes available on the market and the wide range of permissible tolerances have
made it necessary to find an innovative solution for mechanical fittings. While maintaining the nominal
dimensions of the fittings currently available on the market, this new solution has been constructed so that
the same fitting can be used for pipes with differences on external diameters of up to
.075" and differences
on internal diameters of up to .02".
Resistance to pull out
This adapter offers a high degree of resistance to pull out of pipe. Its special clamping system makes it
suitable for every application and ensures a leak tight fit.
Low pressure losses
The internal profile of the adapter (1) has been shaped to obtain a Venturi effect when the fluid passes
through, reducing pressure losses by 20% compared to those created by passages with a similar diameter.
Insulation ring
The fitting is equipped with a rubber insulation element (2) to prevent contact between the aluminium in the multi-layer pipe and the brass fitting,
thus preventing galvanic corrosion generated by the two different metals.
Dual O-ring seal
The adapter is equipped with two O-ring seals (3) and (4) in EPDM to prevent leaks even when operating at high pressure.
Self-adjusting fitting for simple and multi-layer plastic pipes with internal Venturi effect profile to limit pressure losses. 3/4”F
connection. Brass nut and adapter, EPDM seals, EPDM insulation ring, PA 66 GF olive coupling. Medium: water and glycol solutions.
Maximum percentage of glycol: 30%. Maximum working pressure: 10 bar. Temperature range: 5–80°C
(PEX) ; 5–50°C (Multilayer) .
