Ordering Information

Standard Corrugated Sleeves

Siftex maintains a large inventory of corrugated sleeves in all styles, sizes and compounds. Contact your distributor or our sales department for quick pricing, selection and shipment!

Custom Corrugated Sleeves

Because of their molded nature, corrugated sleeves do not lend themselves to easy custom sizes. If you need a connector for a special length, diameter or other characteristic, talk to our sales team today. If we can’t make or modify a molded corrugated connector for your application, we can almost certainly solve your problem with another of our more adaptable connection technologies.
