Dairy Nut
What is a Dairy Nut

A Dairy Nut is a precision-machined sanitary fitting used extensively in dairy, food, and beverage processing industries. Designed to ensure leak-proof connections in hygienic pipelines, dairy nuts are used alongside ferrules, liners, and gaskets to form tight, reliable joints in clean-in-place (CIP) systems.
With a robust design and smooth finish, dairy nuts enable frequent dismantling and reassembly of process lines without compromising hygiene or performance. Their compatibility with standard union fittings ensures interchangeability and ease of maintenance.
Asaid Steel Industries is a trusted Dairy Nut supplier, offering quality-assured products that meet industry hygiene and dimensional standards.
