OEM vs Aftermarket: A Parts Expert's Take on Boiler Parts
OEM or aftermarket — it's one of the most debated questions in the boiler room. Brian Grindstaff has 24 years in boiler parts and a clear answer on when each one is the right call.
Ritchie Ware sits down with Brian Grindstaff, the man behind BoilerWAREhouse, to break down the OEM vs. aftermarket parts decision. They cover form-fit-function rules, when codes and UL listings change the equation, safety device considerations, and how to know when to call an expert.
Making the wrong call on a part substitution can mean code violations, insurance issues, or a dangerous failure. Knowing where the line is — and who to call when you're not sure — can save a tech from a serious mistake in the field.
Brian Grindstaff leads the parts operation at BoilerWAREhouse.com, where the team fields these exact calls daily and can help techs identify the right part — OEM or aftermarket — for their specific application.

Can I substitute an aftermarket part for an OEM boiler part?
It depends on the part. For fittings, hoses, gaskets, and valves, if form, fit, and function match and pressure/temperature ratings are met, substitution is often acceptable. For safety devices, controls, and highly engineered components like blower wheels, you need to verify UL listings, code compliance, and manufacturer specs first.
What is the difference between OEM and aftermarket boiler parts?
OEM parts carry the original equipment manufacturer's part number. Aftermarket parts may come from the same factory but are sold under a different brand or part number, often at a lower price point.
When should I always use OEM boiler parts?
For highly engineered components like burner blower wheels, and for safety-critical devices where the specific UL listing, ASME stamp, or insurance approval is tied to the original part, go back to the OEM.
How do I know if a relief valve substitution is safe?
Verify the set pressure, capacity, and whether it carries the proper ASME stamp for your application — for steam boilers, confirm it has the Section I 'V' stamp, not a Section VIII stamp.
