GROCO Stainless Steel Hose Barb Thru-Hull Fitting - 1-1/4"

The GROCO Stainless Steel Hose Barb Thru-Hull Fitting in 1-1/4" is essential for reliable through-hull plumbing systems, particularly for serious boaters and anglers who require durable, corrosion-resistant marine hardware. This fitting is designed for applications such as raw water cooling, bilge discharge, and livewell circulation, ensuring that it meets the demands of vessels that spend significant time on the water.

Constructed from high-quality stainless steel, this GROCO fitting is engineered to resist saltwater corrosion and galvanic degradation, outperforming lesser brass or bronze alternatives. The ribbed barb design provides a secure grip on standard marine hoses, although double-clamping is recommended for critical applications to ensure maximum reliability. Proper installation involves drilling a clean 1-1/4" hole below the waterline and using appropriate sealing washers and backing plates to prevent leaks.

Ideal for anglers, charter captains, and cruising boaters, this fitting accommodates standard 1-1/4" ID marine hoses and is suitable for various applications, including engine cooling and sanitation systems. With its robust construction, the GROCO fitting is a trusted choice for those who seek long-lasting performance in salt or brackish water environments.
