Dust Caps and Seal Kits
• On flat-face couplings the dust caps are more
important than ever to avoid problems and claims.
Use dust caps!
• The major part of all leakage claims is due to that the
customer have connected with residual pressure in
the nipple and damaged the front seal. To replace is
easy! To replace with the new PUR seal also solve
this issue.
• Flip Dust Caps for DN10 and DN12.5 couplings.
Standard is black with CEJN logo. Other colours and
private branding on request with the right volume.

• The idea is to make comparative laboratory tests on competitor products
• Tests that will be done are:
• Flow test
• Impulse test
• Connection test (residual pressure, pilot pressure etc.)
• Connection force test (dry)
• Burst test
• Leakage test (side loads etc.)
• Surface hardness on nipples
• Most likely we will both get better and worse results than CEJN X-series in the
different tests, but it will still be a help for sales people to respond to
customers in a more professional way.

Conclusions:
• CEJN standard
coupling clearly has
the lowest connection
force
• Competitors have very
small difference
between standard
couplings and
eliminator, except
Voswinkel and CEJN.
Voswinkel has clearly
the highest connection
force with eliminator
• CEJN with eliminator
is on the same level
as competitors
standard couplings
• From an ergonomic
handling point of view

Connection test
Test made with pump pressure on one side and open to drain on one side. When
connected the flow is 15 l/min. This test is much tougher than static/trapped residual
pressure.
Conclusions:
• All brands are quite similar.
• Stucchi A-series which probably is the absolute most common coupling in the world has the worst
results in this test with seal failures in both cases

Burst Pressure Test
CEJN and all competitors fulfil their stated minimum burst pressure in general. There are
some specific results that are lower but I would say within tolerance. The normal variation
in material composition and the results in hardening and surface treatment can affect the
results.
The only thing that really stands out is the low burst pressure on Stucchi FIRG couplings
in disconnected position. They are stating a min burst pressure of 400 bar and they are
just above this. The most common is to have couplings on the machine side which means
that there are substantial risks that the coupling will get pressure impulses when
disconnected. In my mind Stucchi FIRG is a big risk in those cases as the valve pin will
blow out like a bullet from a gun if you get a peak pressure impulse when disconnected.

Ball Indentation Test
Ball indentation on nipple body is measured after three different pressure cycles, after 200
bar (0,5xWP), 400 bar (1xWP) and 600 bar (1,5xWP). The smaller indentations the longer
is the life time of the coupling set. The bigger the indentations are the quicker will the
nipple wear down and finally cause leakage or malfunction.
What we can see in this test is that CEJN X65 has an advantage with smaller
indentations. This advantage is obtained by maximized number of locking balls in the
coupling which gives lower force on each ball and high surface hardness on the nipple
bodies.

Surface Hardness TestThe hardness test is made in the ball groove area which always is hardened. Most of our
competitors are using local hardening which cannot reach as high hardness values and
the hardness drops quickly the further from the surface you get. CEJN uses a case
hardening which reach very high values in the surface and it also has the advantage that
the whole nipple body is hardened, not only in the ball groove.

Pressure Impulse Test
In the impulse test we have chosen to make the test on 400 bar as this is what X65 is
tested on. The requirement is 1.000.000 impulses in connected position and 100.000
impulses in disconnected position. This test was continued to 2.000.000 impulses. Several
products has been tested on each position and the values below are average results.
All contenders manage the requirement in connected position. Disconnected nipples has
also good results, actually way better than needed except on Manuli who only manage
about 52.000 impulses which is below the requirement. On disconnected coupling CEJN
has the best result and Voswinkel and Stucchi FIRG did not reach the target. Stucchi
FIRG is actually dangerous as it shoots the valve as a bullet after one or two impulses at
400 bar.

Conclusions
In the tests we have made it has to be said that all contenders are in general on a very
similar level of performance. We can find some specific tests where CEJN is a little bit
better than the others but we can also see that in some tests has CEJN a bit lower
performance. It is also important to have in mind that this is serial production items and
you will for certain have a variation in performance from batch to batch and piece to piece.
Pros and Cons CEJN compared with competition
+ Small Ball Indentations – Longer life in tough applications
+ High Surface Hardness on nipples - Longer life in tough applications
+ Low Connection Force (dry) – Ergonomics and handling is better
+ Coupling can handle pressure impulses good when disconnected
