Check out the quality of the connector in the picture. That's oldschool, drivergrade quality. I had previously replaced one with a plastic junction, which was a piece of junk. It popped out and blocked traffic. I had to borrow a knife from someone who was yelling at me to move my truck just to cut the hose. Luckily, I had a joint to connect the lines and get going. Definitely buy this one without a second thought. It came with screwon caps and Teflon tape. I applied the tape, tightened it with a 12mm wrench, and there are no leaks. I'm back on the road.
