This newer 90 degree prime spray valve kit upgrades/replaces the older "Set Screw" style prime/spray assembly and is a better design.The older set screw knobs stripped easily. The newer 90 degree uses a retaining clip and they almost never come off.
It's an easy part to put on taking minutes only. Make sure you look at the instructions and put the parts on in the order shown before you put the retaining clips on. (The retaining clips hold very well and are hard to pull off, so get it right before you slip the retaining ring (rings) on.) Tip: A small socket works well to press on the retaining clip.
Includes all the little parts as shown in the colour picture:
1 Seat
1 Stem/Ball Assembly
1 Spring
1 Star Washer
1 Hex Nut
1 Cam
1 Knob
2 Retaining Clips (you only need to install one)
