Schedule 80 PVC Fittings

Schedule 80 PVC (Polyvinyl Chloride) fittings are available for use with schedule 80 or schedule 40 PVC pipe. Schedule 80 PVC fittings are easy to install throughout an entire system or can be used in a single PVC pipe repair. Sch 80 fittings are extremely popular and used in a range of applications like: underground, underwater, industrial applications and chemical processing to name a few.

Sch 80 PVC Fittings Applications

Projects that typically make use of schedule 80 PVC fittings include chemical drainage and processing systems, irrigation systems, water lines, and waste water treatment systems.  Due to a higher wall thickness than schedule 40, schedule 80 PVC fittings are typically used in projects that support high water pressures.

Our Schedule 80 PVC fittings come in a dark gray color. PVC fittings are joined to PVC pipe with solvent cement, threading, flanges, or roll-grooved joining.  As stress is heavier at the joints, it is sometimes beneficial to use a stronger PVC fitting like schedule 80 to maintain the integrity of the system lines. Schedule 80 PVC fittings will fit on schedule 40 PVC pipe with no problem.

We carry a HUGE line of PVC fittings like the standard couplings, tees, bushings, elbows and adapters in all sizes and end types (socket/slip, FIPT, MIPT, spigot). Can't find the part you need? Give us a call and we'll assist you.

Why Use Schedule 80 Fittings Instead of Schedule 40?

Fittings are typically used to join two or more pieces of pipe together. Occasionally, they are also used to cap pipe that leads nowhere. Regardless of their purpose, PVC fittings need to be secure, strong, and able to hold up to the job they are being used for. Schedule 40 PVC is strong for plastic, but some higher-pressure applications require schedule 80 PVC instead. Schedule 80 PVC is a thicker material that can handle higher stress and pressure than its thinner schedule 40 counterpart.

While schedule 80 PVC is stronger than schedule 40, it is still rated for the same temperatures. Both schedules of regular PVC have the same chemical makeup, meaning they can start to break down when heated to temperatures exceeding 140 degrees Fahrenheit. Schedule 40 PVC fittings and schedule 80 PVC fittings are not recommended for hot water transportation, so you will need another material for those types of applications.

Applications for Schedule 80 PVC Fittings

Schedule 80 PVC fittings are to be used with schedule 80 PVC pipe and have many practical applications. These fittings are very commonly used for chemical drainage and processing systems, as well as wastewater management. Most applications that involve high pressure fluids would be perfect for schedule 80 PVC fittings. They are also less likely to bend or crack under pressure. This means these fittings are perfect for building and PVC construction projects and crafts.

In short, our dark gray schedule 80 PVC fittings have a longer lifespan than their schedule 40 equivalents. They can also endure more stress, making them a better choice for just about every job. Schedule 80 fittings only cost a fraction more than schedule 40 fittings, however the performance is nearly doubled. In the end, they give you the most bang for your buck.

Types and Sizes of Schedule 80 PVC Fittings

Schedule 80 PVC fittings come in an extremely wide range of types and sizes. We supply a greater variety of schedule 80 fittings than schedule 40 fittings because they have greater utility and strength. The types of schedule 80 PVC fittings we carry are tees, elbows, 45-degree elbows, couplings, adapters, bushings, caps, plugs, nipples, wye’s, unions, flanges, saddles, crosses, and barbed inserts. The sheer amount of different fittings available speaks to the endless applications these fittings have.

Our schedule 80 PVC fittings come in many sizes. From tiny ¼” fittings to huge 24” fittings and everything in between. Each size of fitting has different uses and strengths for each of the different jobs they do. The smaller fittings will typically be used for home and residential use, while some of the larger sizes would suit industrial settings.

Common Questions about Schedule 80 PVC Fittings

Because we specialize in PVC products and accessories, we receive a lot of questions about PVC. Below are a few of the most common questions that are asked about schedule 80 PVC fittings. If you have any questions that are not listed here, feel free to contact us!

Question: Are schedule 80 PVC fittings more expensive than schedule 40 PVC fittings?

Answer: Schedule 80 PVC is thicker than schedule 40 PVC. This allows it to handle higher pressures from within and without. Because of the thicker walls, schedule 80 PVC products need more material to produce. This makes them slightly more expensive than schedule 40 PVC parts. However, schedule 80 PVC is significantly stronger and is still far less expensive than metal pipe and fittings.

Question: Can schedule 80 PVC be used in hot water applications?

Answer: While schedule 80 PVC is stronger than schedule 40, it still has the same restrictions when it comes to temperature. That is because it has the same chemical makeup and is not subjected to any chlorination processes like CPVC is. The maximum operating temperature of schedule 80 PVC pipe and fittings is 140 degrees Fahrenheit; the same goes for schedule 40. This is too low for hot water to pass through without harming the pipe.

Question: How much stronger is schedule 80 PVC than schedule 40 PVC?

Answer: This question has a few different answers. It all depends what type of strength you are talking about. The most common measurement of PVC pipe and fitting strength is burst pressure. Depending on the size of the pipe, schedule 80 PVC pipe can withstand around 50% more pressure from within the pipe than schedule 40. This makes huge differences in water treatment and irrigation applications.
