Regulatory Approvals

The F.D.A. publishes, through the Code of Federal Regulations, standardized criteria which govern the acceptability of materials used in food contact. The U.S. Department of Agriculture publishes similar standards that mirror F.D.A criteria. Neither agency approves or disapproves products.

With the exception of the 50GP and 65GP Series products all LinkTech couplings comply with applicable F.D.A and U.S.D.A standards for food contact.

NSF Compliance

NSF International develops and publishes consensual criteria that govern the acceptability of materials and equipment used in food and beverage processing.

With the exception of the 50GP and 65GP Series products all LinkTech couplings are produced from materials that comply with most NSF standards for potable water and food stuff.
