If you have a 2 year old track home, you can get what you need at Lowes or Home Depot. Otherwise, you may need to look here. Home Depot has more stuff. East Sac Hardware has more variety.
Every time I go to East Sac Hardware to get a specific part, they have it. The last time I needed a fitting to connect a 1/2"" gas line to a 3/4 connector. It was late so I tried both Home Depot and Lowes. No luck. The next morning East Sac HW had it. They also had the exact parts I needed to fix my sprinklers.
Pros: Varied selection
Cons: More expensive than big box
