Characteristics And Performance<\/strong><\/div>
\n

The P38 is a double-acting low-friction piston seal solution for compact o-ring grooves, that extends the service range above what an o-ring alone is capable of supporting. The P38 is designed for light-duty applications, is particularly suited for small-diameter installations, and due to its size and design, is easy to install. High-performance materials, like HLX, provide outstanding wear and extrusion-resistance properties as well as large range of temperature and media compatibility.<\/p>\n\n\n\n

The P38 is designed to be used in existing dynamic o-ring grooves and does not require any groove modification. A good choice for pneumatic and hydraulic equipment sealing needs, the P38 is proven to extend the service range and seal longevity over stand-alone o-ring installations.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n

Applications<\/strong><\/div>
\n

Small\u2011diameter double\u2011acting piston sealing (core application):<\/strong> Specially designed for small\u2011diameter pistons<\/strong> (from 6mm bore), ideal for mini cylinders, small pneumatic cylinders, precision hydraulic\/pneumatic components with limited space.<\/p>\n\n\n\n

Direct upgrade for standard O\u2011ring grooves:<\/strong> Fits directly into existing dynamic O\u2011ring grooves<\/strong> (AS\u2011568A, MIL\u2011G\u20115514F) without modification; delivers far superior sealing and service life than standalone O\u2011rings; perfect for quick equipment upgrades.<\/p>\n\n\n\n

Light\u2011duty hydraulic & pneumatic equipment:<\/strong> Designed for light\u2011duty applications<\/strong>, suitable for both hydraulic and pneumatic systems; widely used in automation, small fixtures, robots, precision instruments, medical devices and small hydraulic manifolds.<\/p>\n\n\n\n

Medium\u2011pressure high\u2011speed reciprocating mechanisms:<\/strong> Rated up to 350bar<\/strong> with max speed 15m\/s<\/strong>; low friction, no stick\u2011slip; ideal for high\u2011speed small servo cylinders, high\u2011speed valves and mini high\u2011speed cylinders.<\/p>\n\n\n\n

Wide\u2011temperature & multi\u2011fluid environments:<\/strong> Operates from -45\u00b0C to 200\u00b0C<\/strong>; Armorlene\u00ae (e.g., HLX) compatible with mineral oils, synthetic esters, water\u2011based fluids; not suitable for phosphate esters<\/strong>; fits cold, hot and multi\u2011fluid conditions.<\/p>\n\n\n\n

Extremely space\u2011limited installations:<\/strong> Ultra\u2011compact, easy installation; perfect for miniaturized, integrated hydraulic\/pneumatic components like small robots, portable devices, precision instruments and small power units.<\/p>\n\n\n\n

Long\u2011life low\u2011maintenance equipment:<\/strong> Excellent wear & extrusion resistance; longer life and less maintenance than standard O\u2011rings; for continuous\u2011running small automation lines, precision equipment and outdoor small units.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n
