Industrial Applications

1. High-Temperature Steam Sterilization in Food & Beverage Processing

Routing low-pressure water vapor and hot water for Sterilization-in-Place (SIP) operations on food packaging equipment.

Problem Solved

Standard pneumatic tubing degrades or introduces contaminants when exposed to hot steam. This PFA tubing withstands water vapor up to 120 °C and is certified suitable for use with food, ensuring safe, continuous sterilization cycles.

2. Chemical-Resistant Pneumatic Control in Semiconductor and Battery Production

Delivering compressed air and vacuum to wafer handling robots and battery cell assembly machines within cleanroom environments.

Problem Solved

Semiconductor and battery manufacturing require components that do not outgas or shed particles. This tubing meets strict LABS (PWIS) and cleanroom standards while operating efficiently under high pressure and vacuum.

3. High-Ambient Temperature Coolant Lines for Industrial Welding Cells

Transporting liquid cooling water to welding actuators and nearby automation fixtures exposed to intense radiant heat.

Problem Solved

Standard water lines can melt or pose a fire hazard in extreme-heat zones. This UL94 V-0 rated tubing reliably operates in ambient temperatures up to 150 °C, preventing leaks and fire risks.
