Leaking flanges costing you time & money? PTFE seals last 5x longer—guaranteed.

December 10, 2025

Gaskets are vital for ensuring the safety and integrity of industrial systems by providing leak-proof seals between pipe flanges and pressure-containing equipment. For those involved in gasket manufacturing, supply, or usage, understanding ASME standards—particularly ASME B16.20 and ASME B16.5—is essential. ASME B16.5 outlines specifications for pipe flanges and flanged fittings, detailing dimensions, material specifications, and pressure-temperature ratings, while ASME B16.20 focuses on metallic gaskets designed for those flanges, including types like Spiral Wound and Ring-Type Joint gaskets. These two standards are interconnected, as B16.5 establishes the flange specifications that B16.20 gaskets must conform to for compatibility. Adhering to these standards ensures safety, interoperability, and regulatory compliance, making ASME-compliant gaskets highly preferred in critical industries such as oil and gas, power generation, and petrochemicals. Choosing the right gasket requires identifying the flange standard, pressure class, face type, and ensuring material compatibility and dimensional accuracy. It is crucial to stay updated with the latest ASME revisions, as standards evolve to incorporate new technologies and materials. Ultimately, compliance with ASME standards enhances the reliability and performance of piping systems, positioning businesses as leaders in a competitive market.



Leaking flanges draining your resources? Switch to PTFE seals for 5x longer life—guaranteed!



Leaking flanges can drain your resources, both financially and operationally. I understand the frustration that comes with constant maintenance and the potential downtime caused by these leaks. It’s a problem that many industries face, and it’s time to address it effectively.

When I first encountered leaking flanges in my work, I realized that traditional seals simply weren’t cutting it. The frequent leaks not only led to wasted materials but also increased labor costs and reduced efficiency. I knew there had to be a better solution.

Switching to PTFE seals has been a game-changer. These seals are known for their durability and resistance to a variety of chemicals, making them ideal for high-pressure applications. Here’s how PTFE seals can help you:

  1. Longevity: PTFE seals can last up to five times longer than standard seals. This means fewer replacements and less downtime for your operations.

  2. Cost-Effectiveness: While the initial investment may be higher, the long-term savings on maintenance and replacements quickly add up. I’ve seen firsthand how companies can reduce their overall spending by making this switch.

  3. Versatility: PTFE seals work effectively in extreme temperatures and harsh environments. This adaptability ensures that you won’t have to worry about performance issues, regardless of the conditions.

  4. Ease of Installation: Transitioning to PTFE seals is straightforward. With minimal adjustments needed, your team can implement the change without extensive training or downtime.

In conclusion, if you’re tired of dealing with the headaches caused by leaking flanges, consider making the switch to PTFE seals. The benefits are clear: longer life, cost savings, and improved operational efficiency. By investing in PTFE seals, you’re not just solving a problem; you’re enhancing your entire operation for the better. Don’t let leaks drain your resources any longer—take action today.


Stop wasting time and money on leaks! PTFE seals last 5 times longer—try them today!



Are you tired of dealing with persistent leaks that drain your time and money? I understand the frustration that comes with constant repairs and replacements. It’s not just about the inconvenience; it’s about the hidden costs that add up over time.

Let’s dive into the solution: PTFE seals. These seals are designed to last five times longer than traditional options, making them a smart investment for anyone looking to eliminate leaks for good.

Here’s how PTFE seals can make a difference:

  1. Durability: PTFE, or polytetrafluoroethylene, is known for its exceptional chemical resistance and low friction properties. This means that it can withstand harsh conditions without deteriorating, unlike rubber or other materials that may wear out quickly.

  2. Cost-Effectiveness: By switching to PTFE seals, you’ll reduce the frequency of replacements. This not only saves you money on materials but also cuts down on labor costs associated with repairs.

  3. Easy Installation: Installing PTFE seals is straightforward. You don’t need specialized tools or training. Just follow the simple steps provided with your seals, and you’ll have them in place in no time.

  4. Versatility: PTFE seals can be used in a variety of applications, from plumbing to automotive. No matter where the leaks are occurring, these seals can provide a reliable solution.

In conclusion, switching to PTFE seals is a proactive step towards preventing leaks and saving money. Don’t let leaks waste your resources any longer. Make the change today and experience the difference for yourself!
