Garlock THERMa-PUR 4122 FC Ring Face Gaskets

At Industrial Experts, we supply Garlock THERMa-PUR 4122 FC Ring Face Gaskets – a high-performance solution for flange bore sealing under extreme heat and chemical exposure. Manufactured with Garlock’s proprietary fibre-based technology, these gaskets resist temperatures up to 1000 °C while delivering oxidation stability and chemical resistance. The ring face design makes them cost-effective and easier to install where only the sealing surface around the bore requires protection.

Why Choose Garlock THERMa-PUR 4122 FC Ring Face Gaskets?

• High-temperature resistance: continuous up to 1000 °C
• Oxidation and chemical stability – superior to graphite
• Hydrophobic, non-stick surface – easy removal during maintenance
• Bore-focused sealing reduces material use and cost
• Safe, asbestos-free design

FAQ – Garlock THERMa-PUR 4122 FC Ring Face Gaskets

Q1: What temperature can THERMa-PUR 4122 FC Ring Gaskets handle?
They operate continuously up to +1000 °C, making them suitable for extreme thermal applications.

Q2: Are they suitable for high pressure?
Yes – rated to approximately 34.5 bar (500 psi).

Q3: Why choose a ring face instead of full face?
Ring gaskets seal only at the flange bore, which can be more economical and efficient in certain applications.

Q4: How do they compare to graphite?
THERMa-PUR offers better oxidation resistance, easier removal, and lower leakage under thermal cycling.

Q5: Can you cut custom diameters?
Yes, we can supply from 15 mm to 2400 mm with precision cutting.
