Keep your rigging clean, protected, and professional with a purpose-built strain relief that supports hoses exactly where they need it most—at the bulkhead pass‑through. By distributing bend stress, it prevents kinks and chafing that can shorten hose life or compromise steering feel.

Designed for hydraulic steering hose and other marine hose runs, the gripper fitting seals tight to stop drips while the wide protective flange shields the hose from edge abrasion. This kit includes the black flange version; a chrome‑plated flange variant is also available if you’re matching brightwork on deck.

Installation is straightforward: cut a 1-1/4 inch hole, seat the 2-3/4 inch flange, and secure. Note that only bulk hose can pass through this fitting—pre‑made hoses with end fittings will not pass—making it ideal for fresh rigging or hose replacement projects where you can feed the line before crimping or attaching ends.

Built for the harsh marine environment and trusted by boaters nationwide, this strain relief helps you protect your investment, tidy up your rigging, and head for the water with confidence season after season.
