Is FPM the Same as PTFE?

FPM vs PTFE gasket materials, black fluoroelastomer O-ring and white PTFE seal side by side on white background, illustrating chemical resistance comparison.

FPM and PTFE are often confused because they both appear in industrial sealing applications—but they’re not the same material. No, FPM and PTFE are completely different polymers. FPM is a fluoroelastomer rubber, while PTFE is a non-elastomeric fluoropolymer plastic. FPM vs PTFE gasket materials Each has unique properties and use cases. Knowing the differences helps […]

Custom EPDM Gaskets for Spiral Ducts & Dampers: Leak & Noise Prevention

Viton gaskets for chemical vent systems, multiple black rubber seals in concentric sizes, arranged on white background for high-temperature applications.

Leaky duct joints and noisy dampers waste energy and create maintenance problems. The wrong gasket makes it worse. Custom EPDM gaskets provide reliable, airtight seals and effective noise damping in spiral ducts and dampers, improving HVAC system efficiency and longevity. EPDM gasket spiral fitting When standard seals don’t fit or perform, custom EPDM gaskets offer […]

What’s the dimension of Spiral Fitting EPDM Gasket?

Choosing the right gasket for a spiral duct fitting is critical. Too loose, and air escapes. Too tight or misaligned, and you’ll face installation delays and poor sealing. That’s why accurate gasket dimensions—cut length, thickness, profile, and standards—matter so much. Spiral fitting EPDM gaskets are engineered to match standard round duct diameters, typically ranging from […]

Why Use EPDM Gasket in Ventilation Pipe Fittings?

When a ventilation system leaks, the cost is more than just air—it’s energy loss, equipment strain, and even noise complaints. I’ve seen systems fail from one bad seal. EPDM gaskets are widely used in ventilation pipe fittings because they offer excellent resistance to temperature, ozone, UV, and aging. This ensures long-lasting, airtight, and low-maintenance performance […]

Common vent gasket failures and how to prevent them

Even a small leak around a vent pipe can lead to major damage over time—rot, mold, or expensive roof repairs. In my experience, most of these failures trace back to one of just a few common mistakes. The most common causes of vent gasket failure include poor installation, shrinkage, thermal stress, material aging, and physical […]

How to install EPDM vent pipe gasket correctly?

EPDM gasket installation guide for vent pipes, step-by-step process showing cleaning, centering, lubrication, and cross-tightening with tools.

A leaking vent pipe gasket often isn’t the gasket’s fault—it’s the installation. I’ve seen perfect EPDM seals fail just because of a rushed fit or skipped step. To install an EPDM vent pipe gasket correctly, clean the surfaces, center the gasket, apply light lubrication if needed, and tighten evenly. This ensures a long-lasting, airtight seal […]

EPDM vs NBR vs Viton gaskets for vent pipes

Using the wrong gasket material in a vent pipe system doesn’t just lead to leaks—it can trigger system imbalance, corrosion, or even failure under pressure. Over the years, I’ve seen these problems show up in both rooftop flue lines and indoor ducting systems. EPDM, NBR, and Viton are the three most common rubber materials for […]

What is a vent pipe gasket and why use EPDM?

When a vent pipe system leaks, it’s usually not the pipe that fails—it’s the gasket. Over time, poor sealing leads to gas leakage, condensation problems, and system imbalance. I’ve helped many clients avoid these issues by choosing the right gasket material upfront. A vent pipe gasket is a sealing component placed between pipe ends or […]

Material comparison: EPDM vs NBR vs Chlorobutyl grooved gaskets

Grooved gasket material comparison, EPDM, NBR, and Chlorobutyl rubber seals displayed side-by-side with labels for temperature and chemical resistance.

Selecting the wrong gasket material might not cause issues at first—but over time, it leads to swelling, cracking, or leaks. I’ve seen this mistake turn into an expensive rework more than once. EPDM, NBR, and Chlorobutyl are common rubber materials for grooved gaskets, each with specific chemical and temperature resistance. Choosing the right one depends […]

What are the advantages of C-style rubber gaskets?

EPDM C-profile grooved gasket, black rubber seal with dual sealing lips and internal shoulder, designed for mechanical pipe coupling applications.

Choosing the wrong gasket shape can cause leaks, misalignment, or even failed inspections. Many clients ask me, “What’s so special about the C-style rubber gasket?” The answer is: a lot. C-style rubber gaskets offer a fast, flexible, and reliable sealing solution for grooved coupling systems. Their simple profile supports quick installation, consistent compression, and broad […]
