During peak growing seasons or tight project deadlines, a leaking injector is more than a nuisance; it is a code violation risk and a threat to your client's yield. With global supply chains remains unpredictable, waiting for a seal to fail before ordering leads to costly downtime and emergency service calls. Keeping these critical wear items in stock ensures your crews can perform on-site maintenance immediately, maintaining project schedules and keeping your clients' systems operational when the heat is highest.\u003c\/p\u003e\u003cp\u003eThe Dosatron D128R Upper Dosing Seal is engineered specifically for the precise tolerances of the D128R series, offering superior chemical resistance compared to generic O-rings or low-grade alternatives. This specialized component reduces labor costs by ensuring a perfect fit the first time, eliminating the need for repeat visits to address minor leaks. By standardized on genuine Dosatron replacement parts, you ensure the long-term accuracy of the injection system and protect your reputation for high-quality maintenance. Being prepared with a full kit of seals provides a distinct competitive edge by minimizing the turnaround time for critical irrigation repairs.\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 Chemical Resistant Elastomer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eDosatron D128R Series Injectors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComponent Type\u003c\/td\u003e\n\u003ctd\u003eUpper Dosing Seal Replacement Part\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Rating\u003c\/td\u003e\n\u003ctd\u003eMatches D128R System Specifications\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\/Finish\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eManufacturer Certified Replacement Part\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 seal is designed for the D128R series injectors, though we maintain a comprehensive inventory of seals and gaskets for the entire Dosatron line including the D14 and D25 models.

Clean the dosing stem thoroughly to remove any mineral buildup or debris that could compromise the seal. We recommend applying a small amount of silicone-based lubricant to the seal as per manufacturer guidelines to prevent tearing during reassembly. Always follow local plumbing codes regarding backflow prevention when servicing chemical injection equipment.\u003c\/p\u003e","brand":"Dosatron","offers":[{"title":"Default Title","offer_id":52158387388705,"sku":"120620","price":4.4,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/8458\/3969\/files\/120620_PR.png?v=1766409816","url":"https:\/\/asiwsupply.com\/products\/dosatron-d128r-upper-dosing-seal","provider":"ASIW","version":"1.0","type":"link"}
