Direct replacement

Getting the old cracked head off was the hard part (took two people), putting the new one on was easy. Back in business.

Easy to install, perfect fit.

I bought this to replace my 40 year old Clayton Mark 2506 head. Amazingly, the 2575K head fit perfectly for both the supply pipe and the plunger.
After about 10 minutes of adjustments, my hydrant was working like new.
Use pipe dope and tape for a good seal.
