The FTF Short Straight Silicone Joiner with a 51mm inner diameter (part number SSC-007) is built for high-performance applications where space is limited but reliability is non-negotiable. Constructed from durable, multi-layer reinforced silicone, it ensures superior resistance to heat, pressure, and chemical degradation. Perfect for custom intercooler setups, radiator lines, or intake systems, this compact joiner provides a strong, flexible connection that maintains performance under demanding conditions. Ideal for tight engine bays or close-proximity components where a full-length hose is unnecessary.
