C-4509 High-Pressure Carbon-Fibre Gasket Sheet

Description

C-4509 is a special high-pressure gasket sheet developed for the most severe thermal and mechanical conditions. The core composition (carbon fibres + high temperature resistant additives, bonded with NBR) is reinforced with an expanded metal insert to deliver very high compressive strength and excellent resistance to blow-outs under heavy bolt loads. It is particularly effective in alkaline process media and steam service where stability at elevated temperatures and fluctuating loads is required.

Key benefits

---

• Expanded-metal reinforcement — significantly increased compressive strength and improved blow-out resistance for high bolt loads.

• High thermal & mechanical capability — formulated to withstand elevated temperatures and severe load cycles.

• Carbon-fibre + NBR matrix — combines mechanical strength with broad chemical resistance (notably alkaline media and many process fluids).

• Improved stress relaxation behaviour — more reliable sealing under pressure/temperature fluctuations.

• Suitable for critical, high-duty joints — reduces risk of gasket failure in demanding plant environments.

Applications & industries

---

• High-pressure flange gaskets in chemical plants (alkaline process lines).

• Steam lines, superheated steam and equipment subject to thermal cycling.

• Pumps, compressors, heat exchangers, valves and manways where high bolt loads and blow-out resistance are required.

Why choose C-4509?

---

Choose C-4509 when your application demands a gasket that will hold up under very high bolt loads, temperature swings and aggressive alkali/steam conditions. The expanded-metal reinforcement plus carbon-fibre/NBR construction gives superior mechanical integrity and blow-out safety compared with plain compressed fibre sheets — an excellent option for plants seeking longer service life and greater operational safety in critical joints.
