Built with four layers of polyester reinforcement and a 5 mm wall thickness, the coupler is intended for charged-air plumbing such as air intakes, intercooler pipes and other turbo systems. Its wide operating temperature range and rated working pressures make it suitable for performance and replacement applications where durable, leak-free connections are required.\u003c\/p\u003e\n\n\u003ch3\u003eWhat sizes and components are included with this coupler?\u003c\/h3\u003e\n\u003cp\u003eThe kit contains one straight silicone reducer coupler sized to join 2.5\" (63 mm) to 3\" (76 mm) hoses, plus two stainless-steel T-bolt clamps sized to match the coupler.
