Hydraulic Seals and Gaskets: Why Prolon Is the Best Choice

If you're looking to buy hydraulic seals, you've come to the right place. Prolon can help you decide which PTFE or engineered plastic hydraulic gasket best meets your needs or help you design custom seals from the ground up.
At Prolon, we welcome new challenges and helping to solve your problems. From concept to final product shipping, our engineering, sales and manufacturing branches work closely with clients to create the most cost-effective and reliable hydraulic components available.
Each year, we supply millions of standard hydraulic seals to industry partners through seamless manufacturing and delivery. In-house control over each step assures our customers they're getting the best that money can buy.

Prolon uses the latest CNC machining technology. But beyond the standard technology, we optimize our process to make your unique custom hydraulic seals.

Focus on Precision: Statistical Process Control

Once prototype hydraulic seals are approved and production begins, quality control becomes the primary focus. A well-designed gasket must be manufactured precisely so it performs as expected in the real-world setting.
Reliability and consistency are assured through the use of statistical process control (SPC). Descriptive analysis is performed at every step in gasket manufacturing, and this information is used for continuous process improvement. Once the process is stable, SPC keeps a close eye on hydraulic seal tolerances to maintain super high quality. We strive to meet our customers' sophisticated demands.

The Right Choice for Standard or Custom Hydraulic Seal Products

With the diverse services and products we have available, we can meet your needs through standard products. If your needs are unusual, we'll walk with you through the whole custom design process from start to finish.
Precise statistical process control, industry standard materials, reliability and consistency combine in our unique products. We're committed to bringing you quality hydraulic seals that satisfy your current requirements and help your company grow into the future.
