When it comes to industrial and commercial plumbing systems, choosing the right type of fittings is essential for both safety and performance. At LESSO America, we understand the demands contractors and plumbing professionals face across a range of high-pressure applications. That’s why we offer Schedule 80 PVC fittings designed to meet those needs with reliability and durability.

What Are Schedule 80 PVC Fittings?

Schedule 80 PVC fittings are a type of thermoplastic connector designed to handle higher pressure environments than their Schedule 40 counterparts. The term “Schedule 80” refers to the wall thickness of the fittings—significantly thicker than Schedule 40—allowing them to withstand greater internal pressure. While both schedules use the same outer diameter, Schedule 80’s increased wall thickness results in a smaller internal diameter, making them ideal for systems where pressure integrity is critical.

These fittings come in a wide range of configurations, including elbows, tees, couplings, bushings, and flanges, all crafted to support pressurized systems in industrial, chemical processing, or commercial plumbing environments.

Pressure Ratings and Performance

One of the key reasons contractors choose Schedule 80 PVC fittings is their excellent pressure tolerance. At 73°F, Schedule 80 fittings typically handle pressure ratings up to 850 PSI, depending on size and design. This makes them especially useful in applications involving high-flow water distribution, chemical transport, or mechanical systems that demand consistent pressure containment.

Temperature also affects performance. As the fluid temperature rises, the pressure rating decreases, so it’s crucial to assess the operational conditions of each system. That’s why working with a trusted source like LESSO America helps ensure you get the right specifications and guidance for the job.

Advantages for Commercial and Industrial Applications

Schedule 80 PVC fittings offer several advantages for high-demand environments:

• Corrosion Resistance: Unlike metal alternatives, these fittings are resistant to corrosion from moisture, chemicals, and most acids, making them a smart choice for long-term installations.

• Low Maintenance: PVC does not require special coatings or frequent inspections, reducing maintenance costs over time.

• Lightweight and Easy to Install: Compared to metal, Schedule 80 PVC fittings are much lighter, which simplifies transportation and installation without compromising strength.

• Cost-Effective: Despite their strength and durability, these fittings remain competitively priced, offering value without sacrificing quality.

Whether used in cooling systems, wastewater treatment, or pressurized chemical transport, contractors find Schedule 80 PVC fittings to be a dependable option for critical infrastructure.
