1" Blu-Lock Cap 31680

The rotatable seal is the thing I didn't know I needed—it lets me adjust the sprinkler head without loosening anything. Pushed it on, turned the water on immediately, and not a single drip.

The stainless teeth grab the pipe instantly, and that rotatable O-ring seal means I can twist the line into position without worrying about a leak. Pressurized the whole zone right after the last fitting clicked and it held perfectly. Nice not to wait on glue or clamps for once.

My old sprinkler repair took forever with clamps, but this cap just pushed on and held tight immediately. The stainless steel teeth really grab, and the O-ring seal let me turn the water back on with zero wait time. Solid buy.
