i purchased these for an application by size. they worked great. i had tried others that did not work.

I want express my satisfaction with the Alcon Pressure Seal - 1.625" (41.3mm) that we recently acquired. The product has exceeded our expectations in terms of performance and reliability.

Additionally, I would like to commend the Alcon team for their excellent service. The support and responsiveness we received throughout the purchasing process were outstanding,

Thank you for providing such high-quality products and exceptional service.
