An API Certified Specialties Company
Ball & Seat Specialties Co. supplies API-certified ball and seat materials for valve and check-valve service. Every standard material we carry is identified by its API symbol — A1 stainless steel, the B-series cobalt alloys, the C-series carbides, plus silicon nitride and zirconia ceramic.
Ball and seat hardness are stated to the same specification your other suppliers already order against, so switching sources doesn't mean re-qualifying the material.
What we supply
Seven material families across the full API ball & seat range, each with published ball and seat specifications.
How to place an order
Orders are taken by phone so we can confirm material, API symbol, size and quantity before anything ships. Credit card payment is handled on the same call — we do not process card details through the website.
Have your API symbol or material, diameter and quantity ready and most orders can be quoted while you are on the line.
Privacy and terms
Any information you share with us stays private and secure. We do not sell or share customer information with third parties.
