2Set 1-1/2 Inch Duckbill Valve Kit 3853100764 Rubber One Way Check Valve Compatible with Dometic Sealand Toilet Drain Pump System

Feature:【Easy Replacement】This 1-1/2'' black duckbill valve kit can replace the original part number 3853100764 and is compatible with Dometic/Sealand toilet drain pump systems (especially the S series, T series and other models). Its standard 1-1/2-inch interface is consistent with the original component specifications, allowing you to easily install it in place without worrying about size or compatibility issues when replacing it.【Sealing Fastening】As a critical sealing component in vacuum flushing systems, this duckbill valve plays an important role in a one-way switch. It effectively allows sewage to drain in one direction while tightly closing to prevent wastewater or odors from flowing back into the toilet and pump. Regular replacement helps keep the entire sewer system clean, hygienic and functioning properly.【Flexible Material】The duckbill valve part is made of high-quality rubber material, which has a flexible and elastic texture. This material ensures that it maintains good sealing during frequent opening and closing, and is not easy to harden, crack, or lose elasticity due to long-term use, aiming to provide a stable and reliable service life and reduce the hassle of frequent replacement.【Easy to Replace】When you notice that your toilet is not draining properly or has odor problems, replacing the rubber duckbill valve is often the first maintenance step. The process is usually simple: turn off the pump, remove the old valve, and install the new valve in the same direction, without the need for special tools or complex skills.【Two Sets of Packaging】We thoughtfully offer two sets (four duckbill valves). You can use one set for instant replacement to solve current problems; The other set is always in stock as a spare part. This way, the next time something similar happens, you can deal with it immediately without having to wait for the accessory.​Specification:Material: RubberColor: BlackSize: 4.52*4.31cm/1.78*1.70inInner Diameter: 3.25cm/1.28inNote: Please allow for the manual measurement errors and color differences.Fitment:Compatible with Dometic S, T, VHT, and VG Series Pump Numbers Including S12D, S12DAB, S24D, S32D, S115A, S12, 52A, S32, T12, T24, T32 ModelPackage Included:2 Set * 3853100764 1-1/2'' Black Duckbill Valve Kits
