They first turned to a large, well-known seal company that recommended high-durometer <a href=\"https:\/\/www.marcorubber.com\/buna-n-o-rings.htm\">Buna-N o-rings<\/a>.<\/p>\n<p>The equipment manufacturer tested the seals using this material and discovered leakage due to the o-rings being too hard. Unsatisfied with the recommended material, the equipment manufacturer approached Marco Rubber &amp; Plastics for a new solution.<\/p>\n<h3>Application Requirements<\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\">The primary goal was to deliver performance and prevent leakage<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\">The material would need to have to appropriate hardness to prevent leakage<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\">It would need to perform under a high level of pressure<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\">It would also need to maintain performance for long periods of time<\/li>\n<\/ul>\n<h2>The Solution: Proving the Performance of a Nitrile O-Ring<\/h2>\n<p>Realizing that the leakage was caused by the excess hardness of the Buna-N o-rings, our expert engineering recommended a softer Nitrile o-ring. We set up a test for this material as well as HNBR and FKM to prove the viability of this solution to the manufacturer. All materials were 70 Shore A hardness.<\/p>\n<p>Our testing procedure called for the Nitrile o-rings to be placed chamber that was set to -40 \u00baF at 3,600 psi in Nitrogen gas and CNG for 90 hours. The chamber was then rapidly decompressed, and the Nitrile o-rings were analyzed and sectioned to look for damage.<\/p>\n<h2>The Result: Exceeding Industry-Standard Performance<\/h2>\n<figure id=\"attachment_55\" aria-describedby=\"caption-attachment-55\" style=\"width: 300px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-55 size-medium\" src=\"https:\/\/wordpress.marcorubber.com\/wp-content\/uploads\/2021\/02\/nitrile-o-ring-before-and-after-1-300x149.png\" alt=\"nitrile o-ring before and after 1\" width=\"300\" height=\"149\" srcset=\"https:\/\/blog.marcorubber.com\/wp-content\/uploads\/2021\/02\/nitrile-o-ring-before-and-after-1-300x149.png 300w, https:\/\/blog.marcorubber.com\/wp-content\/uploads\/2021\/02\/nitrile-o-ring-before-and-after-1.png 768w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><figcaption id=\"caption-attachment-55\" class=\"wp-caption-text\">Before and after picture showing slight swelling but no evident damage.<\/figcaption><\/figure>\n<figure id=\"attachment_56\" aria-describedby=\"caption-attachment-56\" style=\"width: 278px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-56 size-medium\" src=\"https:\/\/wordpress.marcorubber.com\/wp-content\/uploads\/2021\/02\/nitrile-o-ring-before-and-after-2-278x300.png\" alt=\"nitrile o-ring before and after 2\" width=\"278\" height=\"300\" srcset=\"https:\/\/blog.marcorubber.com\/wp-content\/uploads\/2021\/02\/nitrile-o-ring-before-and-after-2-278x300.png 278w, https:\/\/blog.marcorubber.com\/wp-content\/uploads\/2021\/02\/nitrile-o-ring-before-and-after-2.png 634w\" sizes=\"auto, (max-width: 278px) 100vw, 278px\" \/><figcaption id=\"caption-attachment-56\" class=\"wp-caption-text\">The tested o-rings were sectioned to look for damage inside the material.
