Neoprene (CR)
Chloroprene was the first synthetic rubber, and was developed commercially under the name Neoprene®. Chloroprene rubbers, X-rings, O-rings, gaskets, & custom molded parts contain Chlorine in the polymer to reduce the reactivity to many oxidizing agents, as well as to oil and flame.
Polyurethane (PU, AU)
Polyurethane X-rings, O-rings, gaskets, & custom molded parts generally have two or three times greater tensile strength and wear resistance than Nitrile and comparable polymers. Polyurethane also provides excellent permeation resistance when compared to most rubbers.
PTFE O-Rings
The harshest environments require specialized solutions. Often times, a Canyon Components PTFE X-rings are used in harsh chemical environments. Polytetrafluoroethylene, commonly known as PTFE or Teflon®, is a high-performance fluoropolymer known for its exceptional chemical resistance, low friction, and non-stick properties.

Selection of X-Rings (Quad Rings)
Selecting the right X-ring is crucial for optimal performance in your application. Consider the following factors during selection:
- Material Compatibility: Choose an X-ring material that is compatible with the fluids or gases it will encounter. For example, Nitrile is suitable for oil-based fluids, while Viton is better for high-temperature and chemical applications.
- Temperature Range: Ensure the X-ring material can withstand the operating temperature range of your system.
- Pressure Rating: Select an X-ring that can handle the pressure levels in your application to prevent deformation or failure.
- Size and Fit: Proper sizing is essential. An X-ring that is too large or too small can lead to leaks or premature wear.
- Application Type: Determine if the X-ring will be used in a static or dynamic application, as this will influence material and design choices.
Installation of X-Rings (Quad Rings)
Proper installation is critical to the effectiveness of X-rings. Follow these guidelines to ensure a correct installation:
- Inspect the X-Ring: Before installation, inspect the X-ring for any defects, such as nicks, cuts, or deformations.
- Use Lubrication: Apply a compatible lubricant to the X-ring to reduce friction during installation and prevent damage to the seal.
- Avoid Overstretching: Do not overstretch the X-ring during installation, as this can cause it to lose its shape and sealing effectiveness.
- Align Properly: Ensure the X-ring is properly seated in the groove and that it is not twisted or pinched.
- Use Installation Tools: When necessary, use specialized installation tools to avoid damaging the X-ring.
Maintenance of X-Rings (Quad Rings)
Regular maintenance of X-rings can extend their lifespan and prevent system failures. Consider the following maintenance practices:
- Regular Inspections: Periodically inspect X-rings for signs of wear, cracking, or deformation. Replace any X-rings that show signs of damage.
- Monitor Operating Conditions: Ensure that the system’s operating conditions, such as pressure, temperature, and chemical exposure, remain within the X-ring’s specified limits.
- Clean Regularly: Keep the X-rings and surrounding components clean to prevent debris from causing wear or damage.
- Use the Right Lubricants: Maintain proper lubrication to reduce friction and wear on the X-ring during operation.
- Replace as Needed: Even with proper maintenance, X-rings will eventually wear out. Replace them according to the manufacturer’s recommended intervals or when signs of failure are evident.
