The "MECH Fit" system uses the best combination of
new generation of metal and plastic materials:
Transparent part ofthe external cap (PC )Ultrasonic welding for theconnection of the twoparts of the external cap

Heat-treated special steel
alloy for the gripping sleeve
Double conicalsecurity system

FEATUREEngineering Plastic High Quality,
body of the fitting(PSU or PSU / PPSU blend )How the "MECHFit"
Works?
The exclusive technology of the "MECHFit"
is based on its clamp ring feature, thatgrips the pipe, making it the only press fitting without tools.
The patented "MECHFit" clamp ring is
made from a heat-treated special spring
steel. This unrivaled patented technology comes from the Japanese
automobile industry.
After inserting the pipe into thefitting, the small red Jumping
Pin pushed out from the ringand the clamp ring starts compressing the pipe from the outside, absorbing the dimensionalchanges that occur in the pipe.

Black part of theexternal cap (PC )EPDM for the O-rings

New generation!

Simple and Reliable!

We introduce the new "MECHFit" fitting,the only press-fitting without tools, morereliable than traditional press-fittings, thatis compatible with Multilayer and PEX
pipes.
"MECHFit" connects tightly with both PEX /AL / PEX pipes, without typical problems associated with fitting systems that require
tools.
The new "MECHFit" fitting gives 25 years
guarantee and the snap-on solution
makes connection incredibly fast without
any tool !
An astonishingly simple and reliable solution than traditional press-fittings.

Can you believe in such an apparently
simple fitting system that requires neither
tool nor elaborate training for the installers?
Yes you would. The system is so simple
enough that any person could operate theinstallation.

CLAMP RING METHOD pat.

High Productivity!
This apparent simplicity is an engineering
innovation by COCOMECH, working withthe most stringent Japanese customers
looking for quality solution.
We are encouraged by the success ofthese fittings in the Japanese market
where customers want leak-free, tightunion and pipe fittings. Till date, morethan 50 million fittings have been sold.
The new "MECHFit" is an evolution of toolfree fittings used in Japan for many years,
made by COCOMECH under thorough research and engineering innovation.
The large offerings from the new"MECHFit" fitting system for use in all
kinds of sanitary, heating and chill water ( FCU system ) installations give you
best opportunity for cost down and improvement of productivity.

The key feature of the "MECHFit" clamp
ring is that its spring effect guarantees along-term water tightness connection. For
the constant pressing force applying to thepipe, any possible fluctuation in the pipe
dimension could be absorbed. All the othertool-free fittings, like the push-fit types, arecalled old generation and they are struggling how to absorb the dimensional fluctuation of the pipe.
Actually the pipes never have the nominal
dimensions, either because of the manufacturing tolerance, the standards permit
tolerance in the external diameter and in
the wall thickness of the pipe, or becauseof the dimensional changes that the pipe
suffers when functioning connected to thefitting, the well-known creep effect.
