Technology Update
ONE of the latest additions to the Kapsto
standard range of plastic caps and plugs
from Pöppelmann GmbH & Co are the
GPN 211 flexible protective caps, which
efficiently protect the delicate external
contours of cylindrical parts, such as
bolts, pipe ends, flexible hose and tubing,
against damage.
The bright yellow parts are injection-
mouldedusingahighlyflexiblethermoplastic
polyolefin elastomer and are therefore able
– depending on their nominal diameter –
to compensate relatively large tolerances
between +1mm and +2.5mm. As the caps
adapt to the contours of the part they are
protecting they are suitable, for example,
for use on pipe ends fitted with pressure-
sensitive external O-rings. They are rated
for permanent exposure to temperatures of
up to 120°C and can withstand short-term
peak temperatures of up to 150°C.
The new protective caps are available
in 17 different sizes for outer diameters
ranging from 4 to 26mm. The effective
length of the cap is normally 20mm and
may be up to 30mm in individual cases
of application. The sealing lip around the
open end of the cap ensures a firm seating,
prevents the ingress of contaminants and
raises the inner wall of the cap a slight
distance away from the contour to be
protected. The ergonomically designed
grip tab, measuring approximately 15mm
in length, permits rapid and effortless
removal of the cap after use.
Continually developed and manufactured
by Pöppelmann in its own production
facilities, the standard Kapsto range consists
of over 3,000 different types and/or sizes of
protective plastic caps and plugs, all of
which are immediately available ex stock.
Special versions, such as plugs
combining sealing and assembling
functions, can be designed and developed
by Pöppelmann's own team of application
engineers, in accordance with customer
requirements.
