The GYLON® Style 3522 gasket is made of 100% pure PTFE with no fillers or additives, making the material ideal for the most demanding, high purity requirements.  Industries such as food, pharmaceutical, semi-conductor, recognize the uniformity of GYLON® 3522 that makes it an ideal gasket choice for those critical applications that cannot risk process contamination or premature failure.

Customer

High Purity Pump Manufacturer

Background on Customer's Business

This original equipment manufacturer produces pumps and other in-line equipment for high purity markets such as semi-conductor manufacturing. Such equipment requires excellent chemical resistance and compliance to the most stringent industry standards relative to cleanliness. Clean room assembled, tested and packaged, the sub-components for such equipment are critical to functionality and final certification requirements.

Challenges Faced by Customer

Positioned as an industry leader and supplier of premium grade products, the customer was looking to extend the service life of their high purity equipment. Air operated double diaphragm (AODD) pumps and in-line heaters were targeted and therefore required sub-components that could pass leachable testing and offer superior performance. Historically, gaskets supplied by other manufacturers did not meet the desired purity levels or long term service life expectations

Equipment Operating Conditions

  • Temperature: ambient to 212°F (100°C)
  • Media: nitrogen, clean dry air, strong acids
  • Pressure: up to 100 psi

SOLUTION AND BENEFITS

Leveraging Garlocks's proprietary process for GYLON® manufacturing, Garlock's style 3522 material was recommended for this application. Produced from 100% modified PTFE, GYLON® style 3522 insures a high level of purity and services a wide range of applications. With extremely low permeation rates, minimal void content and a surface finish that is non-absorptive, GYLON® style 3522 made an ideal choice for both the static gasket applications as well as the dynamic diaphragm sealing requirements for this customer. GYLON® style 3522 is qualified and certified to various industry standards such as UPS Class VI, NSF-61, 3A, EC-1935, EC-10/2011 and is TSE and phthalate free, along with ROHS and REACH compliant.

The customer experienced great success with this solution and extended the service life of their equipment.
