Custom Pneumatic Fittings, Pneumatic Seals & More

The CTS Connect line of pneumatic connectors and pneumatic tube fittings all use our proprietary seal materials. These unique materials are manufactured to resist wear and are resistant to all types of fluids and chemicals. The result is a more durable and longer lasting pneumatic seal for low- or high-pressure applications.
