Silicone Reinforced End Cap

Silicone Reinforced End Cap is a high-performance component designed to securely seal open pipework, intake systems, and fluid lines in automotive, motorsport, and industrial applications. Manufactured by AutoSiliconeHoses from premium multi-ply reinforced silicone with a polyester braid, the end cap delivers strength, flexibility, and exceptional heat resistance. Precision-moulded with a smooth internal finish, it ensures a tight, reliable fit for sealing unused or test ports while maintaining long-term durability under pressure and heat. Operating between -50°C and +220°C (peak +250°C) and compliant with SAEJ20R3 standards, the reinforced end cap provides professional-grade performance for demanding environments.

Key Features:

• Internal Diameter Range: 4 mm to 25 mm.

• Wall Thickness: 4 mm across all sizes.

• Working Pressure: 5 bar to 12 bar (varies by size).

• Burst Pressure: 15 bar to 36 bar minimum.

• Overall Length: 60 mm with 50 mm insertable length.

• Temperature Range: -50°C to +220°C continuous, +250°C peak.

• Standard: SAEJ20R3 compliant.

• Brand: AutoSiliconeHoses performance silicone.

Silicone Reinforced End Caps provide a secure and heat-resistant solution for sealing open-ended pipework in high-performance systems. Reinforced with a polyester braid, they maintain structural integrity under boost and vacuum conditions, while the multi-ply silicone construction offers resilience against pressure cycling, ozone, and vibration. The 60 mm overall length with 50 mm insertion depth ensures a strong and stable fit, reducing the risk of leaks or blow-off in demanding applications. Their smooth finish also ensures a professional appearance in the engine bay or industrial setup.

Applications include sealing unused intercooler outlets, intake pipes, coolant lines, and other fluid transfer systems in automotive, motorsport, and industrial environments. Distributed under the AutoSiliconeHoses brand, silicone reinforced end caps deliver strength, flexibility, and long-lasting reliability where high temperatures and pressures are present.
