developments products & Flexible caps to protect external contours of cylindrical parts 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.
