Thanks to the standard PG13.5 thread, this straight connector can be easily mounted in most electrical and industrial applications.<\/span><\/p>\n<p data-start=\"1033\" data-end=\"1491\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">In modern installations, cable protection against moisture, dust and mechanical damage is essential. The AD18.5\/PG13.5 conduit coupling ensures a stable connection between the protective tube and the electrical equipment, contributing to increased safety and reliability of the installation. The IP68 protection rating allows the product to be used both indoors and outdoors, including in environments with high humidity or dust exposure.<\/span><\/p>\n<p data-start=\"1493\" data-end=\"1852\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">An important advantage of this AD18.5\/PG13.5 corrugated pipe connector is the special locking system. The corrugated pipe is firmly fixed in the connector and cannot be accidentally pulled out during operation. At the same time, if disassembly is required, the pipe can be quickly released by pressing the locking ring, without the use of special tools.<\/span><\/p>\n<p data-start=\"1854\" data-end=\"2165\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">The ergonomic design reduces installation time and makes it easy to insert already installed cables into the conduit. For this reason, the AD18.5\/P13.5G conduit connector is frequently used in electrical panels, HVAC systems, industrial installations, automation, lighting and control equipment.<\/span><\/p>\n<p data-start=\"2167\" data-end=\"2368\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Made of polyamide, the AD18.5 corrugated tube coupling is resistant to shocks and temperature variations, this coupling offers a long service life and maintains the integrity of the connection even under difficult operating conditions.<\/span><\/p>\n<h3 data-section-id=\"ko902s\" data-start=\"2370\" data-end=\"2382\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Advantages<\/span><\/h3>\n<ul data-start=\"2384\" data-end=\"2651\">\n<li data-section-id=\"1p5rtw2\" data-start=\"2384\" data-end=\"2419\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Quick assembly without special tools;<\/span><\/li>\n<li data-section-id=\"z7aunl\" data-start=\"2420\" data-end=\"2455\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Compatible with AD18.5 corrugated tube;<\/span><\/li>\n<li data-section-id=\"14hxvqs\" data-start=\"2456\" data-end=\"2480\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Filet standard PG13.5;<\/span><\/li>\n<li data-section-id=\"17uol0d\" data-start=\"2481\" data-end=\"2506\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">IP68 protection rating;<\/span><\/li>\n<li data-section-id=\"14xyk7g\" data-start=\"2507\" data-end=\"2533\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Secure tube fixation;<\/span><\/li>\n<li data-section-id=\"1ry09xl\" data-start=\"2534\" data-end=\"2563\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Simple and quick disassembly;<\/span><\/li>\n<li data-section-id=\"16l5xbh\" data-start=\"2564\" data-end=\"2595\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">High mechanical resistance;<\/span><\/li>\n<li data-section-id=\"5s4a9p\" data-start=\"2596\" data-end=\"2651\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Suitable for industrial and commercial applications.<\/span><\/li>\n<\/ul>\n<h2 data-section-id=\"nva1dh\" data-start=\"2653\" data-end=\"2681\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Frequently Asked Questions (FAQ)<\/span><\/h2>\n<h3 data-section-id=\"m09wz8\" data-start=\"2683\" data-end=\"2724\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">What is this plug used for?<\/span><\/h3>\n<p data-start=\"2725\" data-end=\"2850\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">It is used to connect corrugated tubes to electrical panels, distribution boxes and other electrical equipment.<\/span><\/p>\n<h3 data-section-id=\"s9d2o2\" data-start=\"2852\" data-end=\"2903\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Is a special tool required for assembly?<\/span><\/h3>\n<p data-start=\"2904\" data-end=\"2968\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">No. Installation is quick and easy without special equipment.<\/span><\/p>\n<h3 data-section-id=\"nyowr6\" data-start=\"2970\" data-end=\"3005\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Can it be used outdoors?<\/span><\/h3>\n<p data-start=\"3006\" data-end=\"3074\"><span style=\"font-family: arial, helvetica, sans-serif; color: #000000;\">Yes.
