Review: Excellent connector, secures the wires well, easy to use. As it is tightened the silicone envelopes the connection making it water prooof.
Review: I bought a pack of these to do a diy sprinkler repair, the sprinklers have not worked for over a year. I watched a couple of videos and decided to re-wire the valves and replaced the solenoids. I used these grease caps to connect the zone wires and common wire to the sprinkler wire. Worked like a charm and even my husband was amazed that I fixed it all and repaired the broken sprinklers. I was going to call someone out, but didn't like the price so I did it myself and these grease caps were an easy way to connect the wires.

## Questions & Answers

**Q: Are they re-usable? Can I re-use it to connect a different set of wires later? Thanks.**
A: As mentioned, some of the Dielectric grease is displace by the wires and pressed into the wires.  If you are adding one more wire to the bunch, I see no reason why you can't reuse in this case as you are adding mass to the cavity. If you want to be anal, you could add more Dielectric grease to the nut and wires (after twisting them) prior to reuse of the wire nut; cost is about $0.50 per nut if you are considering material cost. But in a pinch, if you run out of nuts, you can add Dielectric grease to finish the job.

**Q: Does the silicone inside harden over time to help keep the wires inside tight and contained? Thanks!**
A: No the silicone in the wire caps are like Vaseline never gets solid. I have a jar of Vaseline that is around 50 or so years old and it's just like they we bought it.

**Q: How many 12 or 16 gauge wires can these hold in one cap? Thanks**
A: I don't know any thing about 12 gauge wire, but for 16 gauge wire it can hold at least 2 .

**Q: I need to join a bundle of three #14 stranded copper wire.  is the wpconn10 the right choice?**
A: The package lists 2 #14 along with other combinations.  3 #14 is not listed.
