Product Details

HPS Performance Products silicone reducer coupler hose, also called a silicone transition coupler or reducing connector, joins two pipes or hoses of different diameters. It is built from high-temperature, 4-ply reinforced silicone and is made for turbo and intercooler piping, air intake builds, and radiator, heater and coolant systems.

Key Features:

  • 4-ply reinforced construction for heavy-duty pressure connections
  • Meets and exceeds SAE J20 standards for high-performance hose
  • High-temperature capability with a rated range of -65°F to 350°F (177°C)
  • UV and ozone resistant silicone for long service life
  • Thick 5mm wall that resists collapse and helps the hose hold its shape under boost and vacuum
  • Straight reducer design for a smooth transition between different pipe sizes

Applications: Custom turbo and intercooler piping fabrication, DIY air intake systems, radiator and cooling systems, heater plumbing, and marine and industrial use.

Please note: Silicone hose is compatible with water and anti-freeze coolant. It is not compatible with fuel or oil.

HPS reducer couplers give a flexible, durable, leak-resistant connection that handles heat, pressure and vibration in demanding performance setups.
