4 Pack 1-1/2" 385310076 Duckbill Valve Kit Replacement for Sealand Vacuum Generators T12,T14,SW12,SW14,VG2,VG3 “T” and “S” Series Pump

Im always weary about buying after market parts but I tried these duck bills and so far they are working very well! Much less expensive then the name brand. I would buy them again!

These duck bills where easy to install and worked as expected

Such a simple thing and you’d think it’s just a rubber valve. But, the compound they use to make these doesn’t work. I’ve installed these valves multiple times, on rebuild after rebuild, thinking that these are ok. But they’re not. They’ll perform okay for about a month and then they start to harden causing the pump to have extended run time trying to build pressure, then the pump will trigger from pressure loss randomly, and then before you know it you’re turning the system on and off between uses. Well, I replaced seals, pump housings pieces, bellows, vacuum switches, etc. and like a good boy I replaced these valves every time I opened the system, not realizing that these cheap valves have been the issue the whole time. The system would be fine for a little while and then start acting up after a couple weeks. The price of the OE valves is crazy expensive and kept me from buying them, but they have now lasted me 8-9 times longer than these cheap valves. And I don’t know about you but cracking open our vacuum flush system is not on my top ten things to do in life. So, bite the bullet and get the OE.

They fit fine

Replaced worn out valves. Worked out just as hoped.

replacement duck bills at a great price

good quality

Fit was right. Easy to install but only lasted about 6 months before they started to decline. May be cheaper than OEM from Dometic but you get what you pay for. Replaced with OEM from Dometic and we’ll see how it does.
