Tube Guide

The Tube Guide consist of a steel or aluminium or plastic tapered head and an replaceable nylon brush, and it’s used to guide tubes through the sheets and the tube support plates during tube bundles assembling. The nylon brush fits in the tube end, holding pilot firmly in place.


Tube Plugs

Ideal for sealing leaky tubes in condenser and heat exchangers. It is recommended to use our ORTC - one revolution tube cutter to puncture the tube to ensure that pressure can not build up in the tube and cause the plug loosen or blow out.
