During the peak of the growing season or mid-summer heat, you cannot afford the downtime caused by a leaking push rod. Supply chain delays often make small specialty parts difficult to source when you need them immediately. By stocking these essential O-rings now, your crews can perform immediate field repairs, ensuring your clients avoid crop loss or nutrient deficiencies while keeping your service schedule on track.\u003c\/p\u003e\u003cp\u003eThis genuine Dosatron push rod O-ring offers superior chemical resistance and seating properties compared to generic seals that often swell or degrade prematurely. Choosing these OEM components ensures the volumetric accuracy of the D128R and D25 series injectors remains intact, reducing the labor costs associated with repeated troubleshooting and secondary site visits. Maintaining a local inventory of these high-wear parts provides your business with a clear competitive edge through faster response times and reliable system performance in the field.\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-Grade Synthetic Elastomer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eDosatron D128R, D25F, D25RE2 Models\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComponent Type\u003c\/td\u003e\n\u003ctd\u003ePush Rod O-Ring (Part Specific)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Rating\u003c\/td\u003e\n\u003ctd\u003eCompatible with Injector Operating PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\/Finish\u003c\/td\u003e\n\u003ctd\u003eBlack matte finish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eOEM Quality Standards\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eAvailable Models \u0026amp; Sizes\u003c\/h3\u003e\u003cp\u003eThis specific O-ring is engineered for the D128R and D25 series push rod assemblies.

Clean the push rod surface thoroughly to remove any mineral deposits or chemical residue that could compromise the seal. Apply a thin layer of manufacturer-approved silicone lubricant to the O-ring to prevent pinching during reassembly and to ensure smooth movement within the cylinder. Always check for leaks under full operating pressure after servicing the unit.\u003c\/p\u003e","brand":"Dosatron","offers":[{"title":"Default Title","offer_id":52158387519777,"sku":"120622","price":2.89,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/8458\/3969\/files\/120622_PR_1e84bd84-d523-4110-a5e7-844fd6efc5ab.png?v=1766409693","url":"https:\/\/asiwsupply.com\/products\/dosatron-d128rd25fd25re2-push-rod-oring","provider":"ASIW","version":"1.0","type":"link"}
