The standardized coupling head with two claws locks into place with a rotational movement of approximately 45° and allows for quick connection and disconnection of compressed-air lines.\u003c\/p\u003e\u003cp\u003eThe coupling is made of galvanized malleable cast iron, has a claw spacing of 42 mm with double safety cams, and is equipped with an NBR rubber seal. The temperature range extends from −40 °C to +100 °C, and the maximum operating pressure is PN 10. Thanks to the wide range of female thread sizes, from G 1\/4\" to G 2\", the coupling can be flexibly connected to fittings, manifolds, lines, and other compressed air components.\u003c\/p\u003e\u003chr\u003e\u003ch5\u003eBenefits\u003c\/h5\u003e\u003cp\u003e✅ Standardized claw coupling system according to DIN 3489\u003cbr\u003e✅ 42 mm claw spacing with double safety cams\u003cbr\u003e✅ Sturdy, zinc-plated malleable cast iron for professional use\u003cbr\u003e✅ NBR rubber seal for general compressed air applications\u003cbr\u003e✅ Quick locking by rotating approximately 45°\u003cbr\u003e✅ Uniform coupling head within the standard DIN 3489 system\u003cbr\u003e✅ Large through-hole for maximum air flow\u003cbr\u003e✅ Wide range of sizes from G 1\/4\" to G 2\"\u003cbr\u003e✅ Maximum operating pressure PN 10\u003c\/p\u003e\u003chr\u003e\u003ch5\u003eTechnical Specifications\u003c\/h5\u003e\u003cdiv style=\"overflow-x:auto;border:1px solid #d9d9d9;border-radius:10px;\"\u003e\u003ctable style=\"width:100%;border-collapse:separate;border-spacing:0;min-width:680px;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background:#f3f3f3;\"\u003e\n\u003cth style=\"position:sticky;left:0;z-index:2;background:#f3f3f3;padding:10px;text-align:center;\"\u003eFeature\u003c\/th\u003e\n\u003cth style=\"padding:10px;text-align:center;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"position:sticky;left:0;background:#fff;padding:10px;text-align:center;\"\u003eTranslation\u003c\/td\u003e\n\u003ctd style=\"padding:10px;text-align:center;\"\u003eFemale-thread coupling \/ claw coupling\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#fafafa;\"\u003e\n\u003ctd style=\"position:sticky;left:0;background:#fafafa;padding:10px;text-align:center;\"\u003eStandard\u003c\/td\u003e\n\u003ctd style=\"padding:10px;text-align:center;\"\u003eDIN 3489\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"position:sticky;left:0;background:#fff;padding:10px;text-align:center;\"\u003eclaw spacing\u003c\/td\u003e\n\u003ctd style=\"padding:10px;text-align:center;\"\u003e42 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#fafafa;\"\u003e\n\u003ctd style=\"position:sticky;left:0;background:#fafafa;padding:10px;text-align:center;\"\u003eClaw Design\u003c\/td\u003e\n\u003ctd style=\"padding:10px;text-align:center;\"\u003edouble safety cam\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"position:sticky;left:0;background:#fff;padding:10px;text-align:center;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding:10px;text-align:center;\"\u003eMalleable cast iron, galvanized\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#fafafa;\"\u003e\n\u003ctd style=\"position:sticky;left:0;background:#fafafa;padding:10px;text-align:center;\"\u003eGasket\u003c\/td\u003e\n\u003ctd style=\"padding:10px;text-align:center;\"\u003eNBR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"position:sticky;left:0;background:#fff;padding:10px;text-align:center;\"\u003eTemperature range\u003c\/td\u003e\n\u003ctd style=\"padding:10px;text-align:center;\"\u003e−40 °C to +100 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#fafafa;\"\u003e\n\u003ctd style=\"position:sticky;left:0;background:#fafafa;padding:10px;text-align:center;\"\u003eoperating pressure\u003c\/td\u003e\n\u003ctd style=\"padding:10px;text-align:center;\"\u003emax.
