Product Description

Title Line

Our Corner Connector 040E is made from a clear ether-based thermoplastic polyurethane alloy with a tapered infeed end, 110º angled bend and straight drain output end.

It is designed to redirect the clean-in-place (CIP) wash fluid flowing through your process ensuring that your equipment stays dry and your product is free from chemicals used to clean your process machinery. 

  • CIP (clean-in-place) wash processes to replace traditional steel tun-dish and swiveling pipework.

  • Designed for applications where product/material needs to be transported around a bend.

  • Ideal for under compact machinery (i.e. sifter/sieve) where product needs to be redirected into other equipment where there is limited space.
