T-H Marine BSR1KDP Bulkhead Strain Relief Hose Kit – .250–.485 OD, 1-1/4" Hole, Watertight
The T-H Marine BSR1KDP is a bulkhead strain relief fitting kit for routing hose through a bulkhead or panel on a boat. The strain relief distributes the stress from hose bends at the bulkhead penetration point, preventing the hose from kinking, cracking, or pulling loose at the entry point over time. The watertight gripper fitting seals around the hose to prevent water intrusion through the bulkhead opening.
Fits hose with an outside diameter of .250" to .485" and requires a 1-1/4" installation hole in the bulkhead or panel. For bulk hose only — pre-made hoses with end fittings already installed cannot pass through the fitting.

Parts Desk Insights
Best Use Case: The BSR1KDP is the right fitting when you’re routing bulk hose through a bulkhead or panel and need both a watertight seal and strain relief at the penetration point. Without a strain relief, hose that passes through a bulkhead is subject to chafing against the hole edge and stress from bends immediately after the penetration — both of which can cause premature hose failure. The watertight gripper design seals around the hose to prevent water from passing through the bulkhead opening, which is important for any penetration below or near the waterline or in areas exposed to spray. The 1-1/4" hole requirement is the key installation constraint — confirm you can drill or that a 1-1/4" hole already exists in your bulkhead before ordering. Remember this fitting is for bulk hose only: if your hose already has end fittings installed, the fitting cannot be threaded onto the hose.
