More About Double Male Adapters

A pipe/hose fitting adapter is used to connect straight pipe or hose sections, to adapt to different sizes or shapes, and for other purposes. 

Pipe nipple is a length of straight pipe with male threads on both ends. It is one of the most popular category of pipe & hose fittings. It is a connector or a coupling threaded on both ends. Pipe nipples are used to allow items with different threads to be connected together. They are used to fit straight / tapered end hose or pipes. A combination of pipe nipples are recommended for low-pressure discharge and suction service for various compatible liquids and not for compressible products like air, nitrogen or steam. 

A coupling (or coupler) (used in piping or plumbing) is a very short length of pipe or tube, with a socket at one or both ends that allows two pipes or tubes to be joined, welded (steel), brazed or soldered (copper, brass etc.) together.

Alternatively if a short length of pipe with two female National pipe threads (NPT) (in North American terms, a coupler is a double female while a nipple is double male) or two male or female.

If the two ends of a coupling are different (e.g. one NST/NH threaded and one NPT threaded), then it is usually referred to as an adapter.

Great toy for dogs or cats
Color: Clemson Tigers, Size: Large, Color: Clemson Tigers, Size: Large
Both my dog and cat love this treat finding toy. Dog (husky) can work it very quickly- the doors slide a bit too easily for him but the cat also successfully hunts up his treats as well. The quality seems nice and despite their use, still looks brand new.

Quality
Color: Missouri Tigers, Size: Large
So i got this for my dog who was board and distroying the house and or having anxiety attacks. This was a cheap option and he loved it as a beginner puzzle. The covers slide so easily and don't stick like wooden puzzles. The amount of treat pockets is also great. The dog doesn't care what team it is related to and neither do I. If you are looking to keep your too smart dog entertained, tis is for you.
