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-moulded using a highly
flexible thermoplastic 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.
