T-H Marine Bulkhead Strain Relief Hose Kit, Black — Product description

If you run hydraulic steering, the spot where your steering hose passes through the transom or a bulkhead is where trouble starts. T-H Marine's Bulkhead Strain Relief Hose Kit gives that pass-through a clean, watertight home. It grips the hose, kills the kink, and stops the chafe. Powder-coated black, 2-3/4 inch flange, sold as a single fitting.

Hydraulic steering is smooth and strong, but the hose still has to get from the helm pump back to the cylinder at the transom somehow. On a lot of boats that means passing through a bulkhead, a splashwell wall, or the transom itself. Left unsupported, the hose rubs against the edge of that hole every time you turn the wheel or the boat pounds through chop. Over a season or two that rubbing wears the outer jacket, and a sharp bend right at the pass-through can kink the line and choke your steering. This little fitting is the fix.

The Bulkhead Strain Relief mounts over the hole with a 2-3/4 inch flange and grips the hose with a watertight gripper fitting. Instead of the hose leaning on a raw fiberglass or aluminum edge, it rides in a smooth, supported collar. That does two things. It relieves the strain right at the bend so the hose can't kink, and it seals the pass-through so water isn't wicking down the line into the bilge or the rigging tube. On a wet transom that matters.

Hydraulic steering is the standard on bigger outboards and heavier boats because it takes the load off your arms and holds a course without wander. But all that smoothness depends on the hose staying open and intact from the helm to the cylinder. A line under pressure doesn't like a tight bend. Force one and you get hard spots in the wheel, and in a worst case a weeping fitting or a split jacket. Supporting the hose where it changes direction, especially at a bulkhead, keeps the whole system feeling the way it did the day it was bedded in.

The whole thing is powder-coated black, so it holds up to salt spray and sun without the surface corrosion you'd get from bare metal. It's a clean look too, tucked against a dark hull or a splashwell, and it won't flake or rust and streak the gelcoat below it. You get a single fitting in this kit, which is what most single-hose runs need. If your setup routes two lines through the same panel, you'd grab a second one.

We see these on center consoles, bay boats, and bass rigs, anywhere a hydraulic steering hose has to duck through a wall on its way aft. If you've ever pulled a rigging tube apart and found the steering hose worn shiny where it crossed an edge, you already know why this exists. Installation is straightforward. Use the existing pass-through or bore a clean hole, set the flange, feed the hose through the gripper, and snug it down. No special tools, and no cutting into your steering line.

One thing worth saying up front. This is a strain-relief and pass-through fitting for your existing hydraulic steering hose. It isn't the steering hose itself, and it isn't a cylinder or a helm. Think of it as the piece that protects the expensive parts you already installed. Match it to your hose so the gripper seats snug, and if you're not sure of your hose size, measure the outside diameter before you order. Getting that right is what makes the difference between a fitting that grips and seals and one that lets the hose slide.

It's also a spot worth checking during your seasonal once-over. Pop the panel, look at where the hose passes through, and make sure the gripper is still snug and the jacket is clean. Because the fitting seals the hole, you're also keeping spray and rain out of a space that's a pain to dry out later. For a part that costs less than a tank of gas, it saves you the headache of chasing a chafed steering hose mid-season. Rig it once and forget about it.

Frequently asked questions

What does the bulkhead strain relief actually do?

It supports your hydraulic steering hose right where it passes through a bulkhead, splashwell, or transom. The flange mounts over the hole and the gripper fitting holds the hose, which stops it from kinking at the bend and chafing against a raw edge. It also seals the pass-through so water doesn't wick through.

What size is the mounting flange?

The flange is 2-3/4 inches in diameter. It sits over a bored pass-through hole and gives you a clean, finished collar around the hose.

Is it watertight?

Yes. The gripper fitting is made to seal around the hose, so it keeps spray and rain from getting through the pass-through into the bilge or a rigging tube. That's a big part of why it's worth installing.

Will it corrode in salt water?

It's powder-coated black, which holds up to salt spray and sun a lot better than bare metal. Give it the same fresh-water rinse you give the rest of your rigging and it'll last.

Does this include the hydraulic steering hose?

No. This is the strain-relief and pass-through fitting for your existing steering hose. It isn't the hose, cylinder, or helm. Think of it as the piece that protects the steering line you already ran.

How many come in the kit?

This is sold as a single fitting. If you route two lines through the same panel, you'd want to order a second one.

Where should I install it?

Anywhere your hydraulic steering hose has to pass through a wall on its way aft, most often at the transom, splashwell, or a bulkhead behind the console. Set the flange over the hole, feed the hose through the gripper, and snug it down. No special tools needed.

Will it work with my hydraulic steering?

It's built for standard single hydraulic steering hose runs. The important thing is matching it to your hose so the gripper seats snug. Measure the outside diameter of your hose before ordering if you're not sure.

Does it come in another color?

This one is the black powder-coated version. T-H Marine also offers the same bulkhead strain relief in a chrome finish if you'd rather match brighter deck hardware.
