Coupler 3in Black

The Coupler 3in Black (SPE8771) by SPECTRE is a straight tubing coupler engineered for reliable fluid, air, or coolant transfer in industrial, automotive, and equipment maintenance applications. This coupling component connects two 3-inch outside diameter tubes or hoses into a single, continuous line, making it essential for hydraulic systems, cooling circuits, and pneumatic installations where leak-free connections are critical.

Manufactured from durable silicone material, the Coupler 3in Black features a straight design with a 2.25-inch functional length that accommodates standard 3-inch OD tubing on both ends. The black finish provides corrosion resistance and UV stability, making it suitable for both indoor and outdoor installations. The silicone construction delivers flexibility and temperature tolerance, allowing the coupler to maintain integrity across varying operational conditions while resisting degradation from oils, coolants, and mild chemical exposure common in workshop and fleet environments.

Technicians, fleet maintenance teams, and equipment operators benefit from this coupler's straightforward installation—simply slide the tubing onto both ends and secure with hose clamps if required. Its compact footprint (4 x 3.5 x 6 inches) and lightweight profile (0.435 lbs) make it practical for tight-fitting engine bays and confined system layouts. Compatible with any system utilizing 3-inch OD tubing, this SPECTRE coupler is an economical repair and assembly component for pressurized and gravity-feed applications alike.
