They are designed to prevent leakage, protect internal components, and maintain system pressure. Their role is crucial to maintain the efficiency and performance of the system, while extending the cylinder\u2019s life cycle.\r\n\r\nHi-Tech Seals provides an extensive selection of <a href=\"https:\/\/www.hitechseals.com\/products\/seals\/rod-seals\/\">rod seals<\/a> and <a href=\"https:\/\/www.hitechseals.com\/products\/seals\/piston-seals\/\">piston seals<\/a> for single-acting and double-acting systems. They are available in numerous materials and lip configurations to suit different pressures, temperatures, media, and application requirements.\r\n<h2><strong>Main Functions\u00a0<\/strong><\/h2>\r\n1.) Prevent Leakage \u2013 These sealing components maintain internal pressure and prevent media leakage by creating pressure barriers between moving parts. Piston seals prevent pressurized media from bypassing to the opposite side of the chamber, while rod seals stop internal media from escaping the cylinder as the rod extends and retracts.\r\n\r\nThey can adapt to withstand different pressures demanded in the application. When system pressure presses onto the elastomer, it causes the elastomer to expand, conforming to the surfaces being sealed, providing a tighter seal. <a href=\"https:\/\/www.hitechseals.com\/product\/back-up-rings\/\">Back-up rings<\/a> can help support the elastomer to withstand high pressures by keeping the elastomer in place and preventing it from entering the clearance gap.\r\n\r\n2.) Prevent Contamination \u2013 Wipers, in particular, act as a barrier to keep dirt and debris out of the cylinder, preventing external contaminants from entering the system and protecting internal components.\r\n<h2><span style=\"font-size: 18pt;\"><strong>Common Seals for Hydraulic and Pneumatic Cylinders\u00a0<\/strong><\/span><\/h2>\r\n&nbsp;\r\n<table style=\"border-collapse: collapse; width: 100%;\">\r\n<tbody>\r\n<tr>\r\n<td style=\"width: 80.48%;\"><a href=\"https:\/\/www.hitechseals.com\/products\/seals\/o-rings\/\">O-Rings<\/a>\r\n\r\nO-Rings grooves allow the O-Ring to be squeezed diametrically out-of-round even before the pressure is applied. The distortion of the O-Rings is a resilient elastic compound that fills the leakage path, thus creating a seal.\r\n\r\n<img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-5764 aligncenter\" src=\"https:\/\/www.hitechseals.com\/wp-content\/uploads\/2026\/02\/image-12-300x157.png\" alt=\"\" width=\"300\" height=\"157\" srcset=\"https:\/\/www.hitechseals.com\/wp-content\/uploads\/2026\/02\/image-12-300x157.png 300w, https:\/\/www.hitechseals.com\/wp-content\/uploads\/2026\/02\/image-12.png 360w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/td>\r\n<\/tr>\r\n<tr>\r\n<td style=\"width: 80.48%;\">&nbsp;\r\n\r\n<a href=\"https:\/\/www.hitechseals.com\/product\/wipers\/\">Wipers<\/a>\r\n\r\nWipers prohibit contaminants from entering the cylinder and damaging the internal seals and components.
