Irrigation Pipe Gaskets

In agriculture, water is money. Getting the right amount of it where and when it’s needed is tied directly to crop yield and bottom lines. That’s why it’s vital that worn-out gaskets—the number one cause of leaky valves—are replaced as soon as they’re found.. While replacing the valve is easy, finding the part you need and getting it, especially in older systems, can be much harder.

Identifying the Irrigation Pipe Gasket You Need

Browse any gasket catalog, and you’ll quickly be overwhelmed. Do you need a gasket for a drain or non-drain valve?  Should you opt for the same brand name that you had before or go for something customized? What’s the term “crown” mean? How do you pick the right irrigation gasket? Identifying the part you need means analyzing the old ones:

  • Engraved Part Numbers: Some gaskets come with UPCs and logos etched into their surface. Your supplier can match these numbers to what’s in their stock. Unfortunately, because of the stress irrigation valves are put through, these identifying markers are often washed away.
  • Diameter A lot of companies sort their gaskets by width. Just take a small ruler and measure the old piece from edge to edge. This should make it easier to pick the right part. If the old one is broken, join the sides together first. Note, however, that some applications can stretch the gaskets. This can lead to purchasing the wrong size. So, it’s sometimes a good idea to measure the hole or housing itself.
  • Thickness: Some O-ring irrigation gaskets are paper-thin while others can measure an inch or two thick. While you’re measuring the length across the gasket, do the same thing up and down it. Jot this number down somewhere.
  • Drain or Non-Drain: Is this valve used to drain the system? If so, it’s a drain-type irrigation gasket. If the water on top of it stays when the system is turned off, it’s known as a non-drain valve. These are different parts and often found in different parts of the catalog.
  • Hole Diameter: In some circumstances, it’s the rubber that’s missing that’s important. The width of the pole or bolt going through the housing varies widely between applications. Are there three bolt holes or two? Can you see grooves for screws on the inside?
  • Shape: Some gaskets are shaped like mushrooms and others look like sluice gates. Look at the shape of the broken piece, noting down any protrusions or indents. This will make selecting the right piece easier.

In many cases, especially with worn parts, it’s best to send a sample to your supplier. This will allow them to examine them in-depth and determine what irrigation gasket is best for your system.

Why You Should Call Poly-Tek Instead of Going to a Distributor

On a new car, the average OEM tire lasts between 20 and 30,000 miles. This is far below the market average of 60 to 75 thousand miles. By going with a subpar product, car manufacturers save millions of dollars outfitting new vehicles. The same cost-cutting procedures can be found at many OEM suppliers—including those who sell and manufacture irrigation systems. By opting for a custom-injected part, you reap benefits like:

  • Improved Tolerances: The rubber molding companies use is typically of a higher quality than what you’ll get from the supplier. This means your gasket can better handle extreme temperatures and pressures better than the original parts. Because third-party suppliers don’t think of gaskets as an afterthought, we put a lot more care into manufacturing a part that suits your needs.
  • Obsolete Part Availability: Just like with cars, there’s always a new model of irrigation valve hitting the market. And, in many cases, your system will outlast the availability of its gaskets. This leaves you with two choices: replacing the system entirely or allowing a leak to persist for months or years. An injection molding company like ours, that can make a part long after OEM availability has dried up, can extend the life of your system.
  • Customization: Was that old irrigation valve not doing the trick for you? Do you need one that better fits your needs? Companies like ours can adjust existing parts to improve their performance.
  • Cheaper Prices: The parts you get from your supplier often come at a mark-up. This is because profits have to be given to not only the irrigation system manufacturer but also the company that made the O-ring or IRECO type valve you’re looking for. By cutting out the middle person, we can pass savings on to you.
  • Shorter Lead Times: For older units, irrigation valves are often produced on an as-needed basis. When you place an order with an OEM for one of these out-of-stock products, you have to wait for them to find a supplier, place the order, and get the finished parts to you. Our irrigation valve manufacturing process allows us to quickly switch from job to job. So, whether you need a few gaskets or a few thousand, we can get things turned around quickly.

As the above shows, t’s often better to approach a third-party for aftermarket irrigation gaskets than to rely on the company that made your system in the first place. For them, the money often comes from large sales, not the day-to-day maintenance of commercial equipment.
