Plastic (Nylon) Tube Inserts

Prevent tube end erosion and costly retubing of Condensers and Heat Exchangers. PLASTIC TUBE INSERTS offer permanent protection for new tubes or extended life for old tubes already pitted or thinned at the insert section. The flared end of the insert is designed to give smooth venture entrance for the fluid to flow. Nylon inserts are resistant to chemicals and are not affected by oils or greases. These inserts will withstand temperatures to 250 °F.

** Navy Spec. inserts available **

Some sizes also available in 4" lengths. Inquire about additional sizes.
