Once coupled, the connection can thus be mechanically secured against accidental opening. This makes this design particularly suitable for demanding compressed air applications with heightened safety requirements.\u003c\/p\u003e\u003cp\u003eThe coupling has a 42 mm claw spacing, is made of galvanized malleable cast iron, and uses an NBR rubber seal. The temperature range is −40 °C to +100 °C, and the maximum operating pressure is PN 10. The female thread allows for direct mounting on pipes, fittings, and system components.\u003c\/p\u003e\u003chr\u003e\u003ch5\u003eBenefits\u003c\/h5\u003e\u003cp\u003e✅ Holes for additional safety clips\u003cbr\u003e✅ Mechanical lock to prevent accidental opening is available\u003cbr\u003e✅ 42 mm claw spacing\u003cbr\u003e✅ Malleable cast iron, galvanized\u003cbr\u003e✅ NBR rubber seal\u003cbr\u003e✅ −40 °C to +100 °C\u003cbr\u003e✅ Various female thread sizes\u003cbr\u003e✅ Maximum 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 with safety holes\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 spacing\u003c\/td\u003e\n\u003ctd style=\"padding:10px;text-align:center;\"\u003e42 mm\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;\"\u003eAdditional Safeguard\u003c\/td\u003e\n\u003ctd style=\"padding:10px;text-align:center;\"\u003eHoles for safety clips\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"position:sticky;left:0;background:#fff;padding:10px;text-align:center;\"\u003eoperating pressure\u003c\/td\u003e\n\u003ctd style=\"padding:10px;text-align:center;\"\u003emax.
