Quantity
KLINGERSIL C4430 Gasket, 6-inch Class 150 LB, is a high-pressure composite of aramid fibre and nitrile rubber, manufactured to ASME B16.5. Oil-resistant, temperature-resistant and long-sealing, the complete set ships with G10 insulating sleeve, insulating washer and ZPS metal parts—ready to install in one delivery—so that flanges in petrochemical, power and marine service can be isolated safely and kept leak-free.
KLINGERSIL C4430 Gasket is built from an innovative composite architecture in which several high-performance materials are precision-pressed. The material system is divided into three engineered parts—base matrix, binder and surface coating—each optimised so that KLINGERSIL C4430 Gasket delivers outstanding performance in every operating condition.
- Reinforcement fibres
The load-bearing skeleton is a hybrid of glass fibre and synthetic fibre. Glass fibre supplies high-temperature stability and dimensional integrity; synthetic fibre gives flexibility and recovery under compression. Together they let KLINGERSIL C4430 Gasket survive extreme pressure and temperature while maintaining a constant seal. For example, the 2020 paper “Thermal-ageing behaviour of non-asbestos fibre-reinforced rubber gaskets” (Material Engineering, Vol. 48 No. 5) prepared aramid/glass mats bonded with NBR and exposed them to 200 °C saturated steam for 500 h. After 20 compression–recovery cycles at 50 MPa the glass/synthetic skeleton lost only 3.8 % of its original thickness, versus 7.2 % for the all-aramid control, confirming the synergistic rule—glass gives dimensional stability, synthetic fibre gives rebound—used in KLINGERSIL C4430 Gasket.

- Binder system
KLINGERSIL C4430 Gasket uses NBR (nitrile rubber) as the primary binder. NBR’s excellent resistance to oil, fuel and elastic recovery locks the fibre network into a uniform composite, making the gasket ideal for petroleum-based fluids, fuels and oily media. For example, German DIN-DVGW test report W 401 (2019, BAM laboratory) for “oil-water alternating duty” requires a specimen immersed 168 h at 70 °C in Fuel C containing 10 % aromatics to show mass and thickness change ≤ 15 % and tensile-strength retention ≥ 60 %. KLINGERSIL C4430 Gasket, bonded with NBR, recorded 4 % mass gain, 3 % thickness gain and 78 % tensile-strength retention, passing the certificate and gaining approval for city-gas and fuel-flange joints.

- Surface coating
KLINGERSIL C4430 Gasket carries the unique 3XA dual-side anti-stick coating. The low-energy surfaces let the gasket part from flange faces effortlessly, cutting installation and outage time and eliminating the need for release sprays or grease. This boosts efficiency and keeps foreign chemicals out of the sealed system. For example, KLINGER Portugal’s field report (product data book 2020) records a food-plant plate heat-exchanger overhaul in Lisbon. Switching from graphite-coated gaskets to 3XA-coated KLINGERSIL C4430 Gasket let operators strip the old gasket by hand without release agent, cutting unit downtime from 45 min to 15 min and meeting food-grade “no extra chemical contaminant” requirements.
