How to Identify Your Valve:
Hulkey Roberts - Yellow Stem Valve. Hulkey Roberts has made 3 valve sizes: Yellow Stem, Heavy Duty Yellow Stem. The wrenches and Valve bases are not universal.

How to identify which valve you have: open cover, look at the spoke pattern around the pop-up.

• Old Yellow Short Stem - 6 round key holes
• New Yellow Short Stem - 8 Square Key Holes
• Red Stem - Out of Production (No Longer Made)
   

Halkey-Roberts valves are not interchangeable.

We suggest replacing it with a Leafield C-7 valve and valve boot.
