Schedule 80 PVC Crosses

Schedule 80 PVC Crosses are four-way fittings designed to connect pipes at right angles, forming a cross-shaped junction. These fittings feature thicker walls than their Schedule 40 counterparts, providing greater strength and pressure tolerance.

Ideal for demanding applications, Schedule 80 Crosses are commonly used in industrial and commercial environments where reliability and durability are critical. These crosses are compatible with a wide range of PVC fittings and valves, offering flexible integration into diverse piping systems.

Compared to Schedule 40, PVC Schedule 80 fittings are typically gray in color and meet higher performance standards. Their robust construction allows them to handle higher PSI ratings, making them suitable for fluid systems that require superior pressure management. They are especially beneficial in systems that experience frequent pressure fluctuations or exposure to harsh chemicals. These crosses are compatible with Schedule 80 PVC pipes and other Schedule 80 fittings and are available in both solvent-weld and threaded configurations for various application needs.

Maxx Supply offers Schedule 80 Crosses in a variety of sizes, from 1 1/2" to 4", ensuring versatility across many plumbing and construction projects. Each fitting is manufactured to meet ASTM D1784 and NSF standards, ensuring consistent quality and compliance with industry requirements.

Whether you are building a new system or upgrading an existing one, these crosses provide a secure, leak-resistant solution. In addition, these fittings are commonly used alongside tank adapters, insert fittings, and both male and female adapters to create reliable and efficient configurations.

Schedule 80 PVC Crosses integrate seamlessly with other components such as PVC duct fittings, PVC valves, EPDM gaskets, and swing check valves—particularly in applications that require fluid direction control and backflow prevention. Their ability to withstand chemical exposure and physical stress makes them a valuable component in systems ranging from irrigation to chemical processing.

Choosing the Right Schedule 80 PVC Cross for Your System

When selecting between Schedule 80 and Schedule 40 Crosses, consider the demands of your system. Schedule 80 Crosses are built for high-pressure environments such as wastewater treatment plants, chemical processing facilities, and heavy-duty fluid transfer systems.

Thicker walls and industrial-grade material make Schedule 80 PVC Crosses the preferred choice for commercial and professional use. If your application involves the use of a pressure switch or experiences temperature changes, the added durability of Schedule 80 PVC can prevent cracks or joint failures over time.

Cross Configuration Options

  • Most Schedule 80 Crosses are designed as Slip x Slip x Slip x Slip fittings.
  • Threaded versions may be available for installations that require disassembly or maintenance.
  • Reducing crosses allow connections to smaller diameter pipes, making them ideal for branching supply lines from a main feed.
  • Available with clear PVC options for systems that require visual flow inspection.

Selecting the Right Size

  • Available sizes typically range from 1 1/2" to 4".
  • Always confirm that the nominal pipe size matches the inner diameter (ID) of your PVC pipe system.
  • Consider system flow rate and required pressure handling to determine the best size for optimal performance.

Installation Guidelines

  • Use PVC primer and solvent cement for secure slip connections.
  • For threaded connections, pair with a compatible male adapter and seal threads using PTFE tape or thread sealant.
  • Always pressure-test your system prior to operation to ensure leak-free connections.
  • Install EPDM gaskets where needed to enhance sealing, particularly in high-pressure or chemical transport applications.

Support & Stress Considerations

  • Because Schedule 80 Crosses intersect four pipe runs, it's essential to support nearby piping to prevent stress and joint failure.
  • Account for thermal expansion and allow for slight movement when appropriate to prevent damage over time.
  • Reinforce areas where the cross connects with long vertical or overhead piping to reduce mechanical load.
