PRESS-FIT – PERFECTING YOUR PRESS (PROVIDED BY MM KEMBLA)
ACTION
WHY?
1.
Deburr the end of the
copper tube on both the
inside and outside
This is critical for press fitting connections, as
any burrs on the tube can damage the o-ring and
cause failure of your connection. It also minimises
turbulence and pressure loss.
2.
Mark the insertion depth on
your tube as per the product
installation instructions..
Correct insertion depths are fundamental to a
perfect press. Incorrectly inserted tube can lead
to failure of your connection. Marking the insertion
depth will ensure that any tube movement is
detected prior to pressing.
3.
Ensure you have the
correct fitting for the
application.
Press fittings are currently available for different
applications. Not all o-rings are suitable for all
applications, choosing the correct fitting is critical
to the integrity of your press connection. Refer
to product literature or contact your supplier for
application suitability.
4.
Check the sealing element
is correctly seated within the
fitting
Missing or damaged o-rings will lead to a failed
connection. The o-ring is integral to a complete
press connection.
5.
Ensure the jaw profile
is free of debris, grease or
damage. Jaws should be
cleaned after every use.
Any debris, grease or damage on a jaws inside
profile can lead to damage to the fitting upon
pressing.
6.
When closing the press jaw
onto the fitting, ensure the
jaw is placed square and at
right angles to the fitting.
A misalignment of the jaw and fitting can lead to
a failed press connection. Jaw and fitting should
always be aligned prior to activating the press.
