Westar® RU and RS Lined Seals

Injectable drug delivery and containment can be a challenge for drug manufacturers, especially as regulations and quality standards are increasing and as biologic drug products present new challenges in their sensitivity and dose volume. At West, we work closely with our customers to understand industry trends, the challenges our customers face, and we work by their side to drive new innovations to support their work to deliver medicines to the patients that need them.

As customer needs rapidly change to meet these new and unprecedented accelerated timelines, West’s steam-sterilized, ready-to-use Westar^® and Westar^® Select elastomer components play a critical role. They simplify component preparation and allow customers to focus on other aspects of the drug filling process.

Focused on meeting customer needs in different markets and regions, West offers two types of washed Ready-to-Sterilize (RS) rubber closures: Regional-Washed RS and Westar^® RS.
