Engelhardt answers yes to both \u2014 and the second one is unusual for a plumbing component supplier.<\/p>\n      <p class=\"eh-qs-desc-lead\">IATF 16949 is the automotive-industry quality standard.

Because Engelhardt designs and cuts its own tooling on German Roeders, Makino, and Standy machines, a tolerance problem found at first sampling is corrected on the same site \u2014 not negotiated across a separate toolmaker.<\/p>\n          <p class=\"eh-qs-body\">The test center carries the equipment to verify what the certifications promise. Salt-spray corrosion testing checks plated brass and stainless parts; a moving-die rheometer and Mooney viscometer control every rubber batch; humidity and heat-aging chambers confirm a seal will still seal after years of service. That compound-control discipline carries across our broader precision molding capability.<\/p>\n          \n          <blockquote class=\"eh-qs-quote-block\">\n            <div class=\"eh-qs-bracket-tl\" aria-hidden=\"true\"><\/div>\n            <div class=\"eh-qs-bracket-br\" aria-hidden=\"true\"><\/div>\n            <p class=\"eh-qs-quote-text\">&#8220;On a drain assembly, the part that fails first is almost never the body \u2014 it is the seal.
