Daughtridge Sales Co., Inc. specializes in Wika diaphragm seals, thermometers and related items. We have been serving the needs of the industrial and plumbing supply communities with Wika diaphragm seals since 1970. Presently, Daughtridge Sales Co., Inc. has over $1 million in inventory. This allows us to ship most orders the same day that we receive them. Because of the large number of Wika diaphragm seals that we carry in inventory, we are unable to include pricing on this website. If you have specific requirements, please call or email us and we will gladly furnish you with both pricing and availability. If you have any comments or questions concerning our products or services including Wika diaphragm seals feel free to call us at 1-800-967-7507.
