## Description

Your sprinkler system represents an important investment. Whenever water comes in contact with metal and electricity, there is potential for corrosion. The risk is highest on DC Voltage systems, like some 2-wire irrigation controllers, but it can still be a risk for standard 24 VAC irrigation and landscape controllers. Easy Seal waterproof wire connectors and direct burial grease tubes (also known as “grease caps”) are a smart way to protect your investment. Easy Seal waterproof wire connectors are ideal for 24 VAC solenoids in valve boxes, while grease tubes are ideal for 2-wire and direct burial applications. Typical installation of Easy Seal connectors is to directly push the solenoid and sprinkler controller wire into the cap and twist it. You should not reuse waterproof wire connectors. Typical installation for the grease tube is to push the decoder and solenoid wire into the wire nut, twist it, insert the wire nut all the way into the tube, and lock the lid into place. Note: Turn off power before installing or removing waterproof wire connectors. For use in accordance with local and national codes only.

Review: Easier to use than expected. - I had never used grease caps before but I got these when I had to totally rewire my 14 station lawn irrigation system. They installed far easier than I had expected (based on some reviews I had read). They even worked well for the ground circuits where 4 to 6 wires were joined together in one cap. As others have said, finish all your wiring and completely test your system BEFORE installing the caps. You don't want to be pulling these things off and redoing them once you have installed them. The grease could get very messy.
Review: Worked as Advertised - Perfect solution for wiring Irrigation zones in box Protecting the wiring would highly recommend and purchase again!!!

## Questions & Answers

**Q: For what gauge wire are these intended?**
A: This cap is for 16 to 20 gauge wire, and is not to be used with voltage exceeding 24 VAC.

**Q: do you offer a cap that will accmodate a 14 to 12 guage wire size?**
A: These caps likely will not work with that gauge of wire, as the wire is too thick.

**Q: what is the grease cap for? I don’t see one on my current system.**
A: The grease caps are used to waterproof the the wires. You screw the wires into the orange cap then you stick the orange cap into the grease cap then close the grease cap with wires extending from each end. The grease caps are not necessary but they are another level of protections for the wires.

**Q: What is the size of grease cap tube diameter & height.  do not include the square base**
A: The tube itself is 2.25" long, with a 0.5" diameter.
