But the multi-step assembly, left to the installer, created a recurring problem: the nylon ring or the conical rubber seal could be left out during assembly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On a visible fitting, that kind of mistake is caught immediately. On a fitting that ends up buried with the pipe, it only surfaces once water starts leaking \u2014 often too late, and far more expensive to locate and fix.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The solution<\/strong><strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">We proposed rethinking the product itself, not just the material.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The first step was eliminating two separate components \u2014 the nylon ring and the conical rubber seal \u2014 and replacing them with a single part: a glass-fiber-reinforced PA6.6 insert, overmolded directly with a rubber compound certified to KTW standards for contact with drinking water. No more loose parts that need to be positioned correctly one by one: the subassembly arrives exactly as it should be, with no risk of separation or misalignment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The second step is the one we worked on the longest, and it\u2019s also the part we\u2019d rather walk you through in person than spell out in writing: a design solution that smartly separates two functions \u2014 mechanically retaining the pipe and sealing against leaks \u2014 so that fluid pressure, instead of being a risk to the seal, becomes a factor that reinforces it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The third step was our own initiative: we proposed pre-assembling the entire fitting at the factory, with the new subassembly already fitted inside the connector body (the brass components remained supplied and assembled by the customer). The result for the installer: nothing to assemble, nothing to forget. Just insert the pipe and tighten.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>The result<\/strong><strong><\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>From 4 separate components to a single overmolded subassembly that cannot be partially assembled<\/li>\n\n\n\n<li>A seal that performs better under pressure, not worse \u2014 the opposite of what happens with many traditional solutions<\/li>\n\n\n\n<li>A single supplier for the critical component, instead of two materials to manage separately<\/li>\n\n\n\n<li>No chance for the installer to leave a part out<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The strongest validation? The solution we developed later turned out to be original enough to be patented \u2014 an indirect but concrete acknowledgment of the work behind it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>HTP designs and manufactures overmolded rubber-to-metal and rubber-to-plastic components for technical applications where mistakes aren\u2019t an option.
