Individual Pull Thru Purge Baffles
By Pipe/Tube Size & Schedule - 1.5" (45mm) -to- 16" (420mm)
Control your purge, reduce gas usage, and improve weld quality.
These Individual Pull Thru Purge Baffles are designed to simplify pipe and tube purging by isolating the weld zone—helping you achieve cleaner welds while using less gas.
Built with high-temperature silicone rubber and a durable stainless steel center mandrel, these baffles are engineered for long-term performance in demanding welding environments.
Why Use Pull Thru Baffles?
- Lower Gas Usage: Reduce purge volume by sealing off the weld area.
- Cleaner Welds: Maintain proper purge environment to prevent oxidation.
- Faster Setup: Simple pull-thru design makes positioning quick and easy.
- Wide Range: Available for pipe sizes from 1.5" to 16".
- Reusable Design: Built for repeated use in shop or field applications.

Are these reusable?
Yes. They are built from durable materials for repeated use in demanding applications.
What sizes are available?
These baffles cover pipe sizes from 1.5" to 16", depending on the selected option.
Why is purging important?
Proper purging prevents oxidation, improves weld integrity, and reduces rework.
