Coupler 3in PVC w/Red Insert

The Coupler 3in PVC w/Red Insert is a straight tubing connector designed to join two 3-inch inner diameter (ID) hoses or pipes in fluid transfer, pneumatic, and low-pressure hydraulic applications. This coupling is ideal for contractors, maintenance technicians, and DIY enthusiasts who need a reliable, cost-effective solution for connecting rigid or flexible tubing systems. Whether you're assembling sprinkler systems, pneumatic lines, or general fluid distribution networks, this plastic coupler provides the straightforward connection required for efficient system operation.

Manufactured by SPECTRE, this coupler features a plastic construction with a red insert that enhances visibility and aids in system identification during installation and maintenance. The straight design eliminates angular bends, maintaining consistent flow and reducing turbulence within the connected lines. Measuring 3-1/4 inches in length with a compact footprint of 4 x 3.5 x 6 inches, it fits easily into tight spaces while accommodating both standard and specialized tubing sizes. The red insert provides color-coded functionality, making it simple to differentiate between multiple coupled systems or fluid types in complex installations.

This coupler is best suited for applications requiring temporary or semi-permanent tubing connections in agricultural, industrial, and residential settings. Installation is straightforward—simply insert tubing ends into the coupling ports until properly seated. The 0.415-pound weight ensures minimal strain on support structures while remaining durable enough for continuous use. Compatible with standard 3-inch ID tubing and hoses, this connector is an essential inventory item for maintenance kits, equipment repair, and system expansions across multiple industries.
