API Certification

CRC Wellhead is proud to announce we have successfully maintained our American Petroleum Institute API Q1 Registration and API 6A Certification after our most-recent audit was completed 24 July 2026.

CRC delivers industry-compliant products to our customers that they can use in their applications knowing they meet the strict requirements of API.

API Q1 registration is the gold standard for the oil and gas industry and we put a lot of effort into maintaining our registration. Our API Q1 registration number, API Q1-4221, is proof our robust quality system complies with API Q1.

Our API Certificate of Authority, 6A-2231, allows us to monogram appropriate parts with the API logo and our certificate number. Not all parts are eligible to be monogrammed, and our team of engineers works with our customers to help the customer, and the customer's customer, get the correctly monogrammed parts in their systems.

At CRC Wellhead, we know our customers need approved products made correctly.
