When seals fail, chemical dosing accuracy drops and leaks occur, leading to uneven crop growth, nutrient deficiencies, or total system shutdowns. With summer heat and high-demand irrigation schedules looming, you cannot afford to wait on back-ordered components or delayed shipping. Securing these essential wear parts now ensures your crews can perform immediate field repairs without losing days to lead times. Proactive maintenance keeps your client projects on track and prevents the costly cleanup of chemical spills or wasted fertilizer.\u003c\/p\u003e\u003cp\u003eThe Dosatron PDI781 Plastic Push Rod Seal is engineered for superior chemical resistance compared to generic aftermarket gaskets. By utilizing high-grade materials specifically formulated for fertilizer and chemical injection, this seal maintains its structural integrity under constant friction and pressure. Choosing authentic Dosatron components reduces the frequency of service calls and extends the service life of the entire injector assembly. Having these seals stocked in your service trucks gives your team a competitive advantage by allowing for rapid, first-visit resolutions while maintaining the precise dosing standards your clients expect.\u003c\/p\u003e\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eHigh-Performance Chemical-Resistant Plastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eDosatron D14 Series Injectors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003ePDI781\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003ePush Rod Internal Sealing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Rating\u003c\/td\u003e\n\u003ctd\u003eStandard Dosatron Operating Pressures\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\/Finish\u003c\/td\u003e\n\u003ctd\u003eOpaque \/ Natural Plastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eAvailable Models \u0026amp; Sizes\u003c\/h3\u003e\u003cp\u003eThe PDI781 is a specific replacement seal designed for the D14 series push rod assembly.

Apply a light coating of manufacturer-approved silicone lubricant to the seal surface to facilitate smooth movement and prevent pinching during installation. Always verify that the seal is seated squarely in the groove to maintain proper suction and prevent leaks. Consult the specific D14 series service manual for torque specifications and sequence during reassembly.\u003c\/p\u003e","brand":"Dosatron","offers":[{"title":"Default Title","offer_id":52158390829345,"sku":"123637","price":5.06,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/8458\/3969\/files\/123637_PR.png?v=1766256996","url":"https:\/\/asiwsupply.com\/products\/dosatron-pdi781-plastic-push-rod-seal","provider":"ASIW","version":"1.0","type":"link"}
