Wingnut & Rubber Seal – Replacement Set for DIY Cups
This is a four pack of wingnuts and seals – so a total 8 piece’s.
Keep your watering system working exactly as it should with our Wingnut & Rubber Seal Replacement Set, designed specifically for our Automatic, Hen H20 and peck-activated DIY drinking cups. This set will fit most of the DIY Lubing Cups available on the market (however, we only guarantee that they fit our product).
Over time, wingnuts can loosen and rubber seals can wear or perish, leading to frustrating leaks and wasted water. This simple replacement set allows you to refresh your existing DIY cups without needing to replace the entire unit, saving time, money, and water.
Each set includes a durable wingnut for secure fastening and a flexible rubber seal to create a tight, leak-free connection through buckets, pipes or water containers.
- Stop slow drips and leaks
- Restore proper water flow to cups
- Extend the life of your DIY watering system
- Quick and easy to install, no tools required
Perfect for:
- Fixing leaking DIY cups
- Replacing worn or lost parts
- Keeping spare seals on hand for quick maintenance
Tip: If you notice moisture around the base of your cup or inconsistent water levels, it’s often the seal, not the cup, that needs replacing.
