The symmetrical system features a standardized coupling head with a 42 mm claw spacing and is locked by turning it approximately 45°. This allows compressed-air hoses to be connected quickly to other couplings and connection types within the system.\u003c\/p\u003e\u003cp\u003eThe coupling is made of galvanized malleable cast iron and is equipped with an NBR rubber seal. Depending on the hose size, versions with or without a safety collar are available. For a particularly secure hose assembly, Krause K+K recommends the version with a safety collar in combination with a matching Type B hose clamp according to DIN 20039 with safety claws. The temperature range is −40 °C to +100 °C, and the maximum operating pressure is PN 10.\u003c\/p\u003e\u003chr\u003e\u003ch5\u003eBenefits\u003c\/h5\u003e\u003cp\u003e✅ Robust hose coupling for professional compressed-air applications\u003cbr\u003e✅ Standardized claw coupling system according to DIN 3489\u003cbr\u003e✅ 42 mm claw spacing with double safety cams\u003cbr\u003e✅ Galvanized malleable cast iron and NBR rubber seal\u003cbr\u003e✅ Versions with and without a safety collar\u003cbr\u003e✅ Quick locking by turning approximately 45°\u003cbr\u003e✅ Large through-bore for high airflow\u003cbr\u003e✅ Wide size range for different hose inner diameters\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\u003cthead\u003e\u003ctr style=\"background:#f3f3f3;\"\u003e\u003cth style=\"position:sticky;left:0;z-index:2;background:#f3f3f3;padding:10px;text-align:center;\"\u003eFeature\u003c\/th\u003e\u003cth style=\"padding:10px;text-align:center;\"\u003eValue\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\u003ctbody\u003e\u003ctr\u003e\u003ctd style=\"position:sticky;left:0;background:#fff;padding:10px;text-align:center;\"\u003eDesign\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003eHose coupling\u003c\/td\u003e\u003c\/tr\u003e\u003ctr style=\"background:#fafafa;\"\u003e\u003ctd style=\"position:sticky;left:0;background:#fafafa;padding:10px;text-align:center;\"\u003eStandard\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003eDIN 3489\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd style=\"position:sticky;left:0;background:#fff;padding:10px;text-align:center;\"\u003eClaw spacing\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003e42 mm\u003c\/td\u003e\u003c\/tr\u003e\u003ctr style=\"background:#fafafa;\"\u003e\u003ctd style=\"position:sticky;left:0;background:#fafafa;padding:10px;text-align:center;\"\u003eMaterial\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003eMalleable cast iron, galvanized\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd style=\"position:sticky;left:0;background:#fff;padding:10px;text-align:center;\"\u003eSeal\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003eNBR\u003c\/td\u003e\u003c\/tr\u003e\u003ctr style=\"background:#fafafa;\"\u003e\u003ctd style=\"position:sticky;left:0;background:#fafafa;padding:10px;text-align:center;\"\u003eTemperature range\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003e−40 °C to +100 °C\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd style=\"position:sticky;left:0;background:#fff;padding:10px;text-align:center;\"\u003eOperating pressure\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003emax.
