Industrial grade seals are used to prevent leaks that can lead to the contamination of processing liquids and gases. Different types of pneumatic face seals include rod, symmetric, piston, and axial seals that are used in pneumatic cylinders and valves or other applications involving rotary and reciprocating motion. Pneumatic connector seals are installed into shafts and housing bores to provide a leak-free connection and can be used with smooth, rough or threaded ports.  

Pneumatic Connector Seals for Industrial Applications

CTS Seal

A durable, reliable seal is critical for preventing gas and fluid leak that can impact performance or result in product failure. If you have a leak testing or filling application, CTS has industrial seals or pneumatic connectors that will fit your need.
We have designed and manufactured standard and custom industrial grade seals for more than 30 years and offer over 1000 different standard industrial seals in all shapes, sizes and hardnesses. Chances are CTS has a seal for your sealing application, saving you time and money in expensive tooling.

Custom Precision Gaskets for Non-Standard Applications

Pneumatic face seals from CTS have special designs to fit most openings including: threaded, smooth, and much more. Material options range from different hardness, high tensile strength, and chemical resistant compounds that fit our customer manufacturing processes. We also have seals designed for fine leak applications where permeations may be a problem.

For non-standard applications, we design custom seals that are manufactured to contour to the customer part openings for a reliable performance based on your exact specifications. Let us take over where off-the-shelf solutions don’t work.

Bullet and Inverted Pneumatic Face Seals

We offer bullet and inverted bullet face seals that can be used for a variety of openings. The seal point of our pneumatic face seals includes flat, bullet nose, inverted nose and tapered stem options in different sizes and styles. We offer both in-stock and custom pneumatic face seals based on your requirements.

Selecting or Designing Your Industrial Grade Seals

Important factors for determining your pneumatic connector seal requirements include:

  • Dimensions of your shaft and housing
  • Maximum operating speed and pressure
  • Operating temperature
  • Vacuum rating
  • Precision gasket material

Selecting a pneumatic face seal with the right dimensions is critical for effective sealing, but material choice is also important. Your precision gasket material needs to be chemically compatible with the type of processing gas used in your pneumatic application and must provide the appropriate level of tear strength and hardness to prevent the gasket from failing.
Material type also determines the amount of pressure your pneumatic connector seals can tolerate. For applications involving higher pressure levels, your precision gaskets will likely require a harder material.
We utilize three material types to produce our industrial grade seals:

  • Standard urethane for general purpose applications
  • Premium urethane for extended wear life
  • FDA-approved urethane for medical and food contact applications
