Jabsco Pumpguard In-Line Strainer, 1/2 in NPT Ports, Clear Housing, Stainless Steel Screen

Overview

The Jabsco 36400-1000 is an in-line Pumpgard strainer with 1/2 inch male NPT threads and a 40 mesh stainless steel screen for the pump intake side of the system. It sits ahead of the pump to catch rust, scale, and other tank debris before that material reaches valves and diaphragms.

This version uses a clear housing, so it is easy to check the screen without taking the unit apart. The bowl screws off for cleaning, and the strainer can be installed in any position as long as it is fitted before the pump. Overall size is about 4 inches long, 3 inches wide, and 3-1/2 inches high, which makes it easier to place in tight lockers, under berths, or near a freshwater pump set.

On board, this is a practical fit for freshwater pressure systems and other 1/2 inch NPT pump inlets where finer screening is wanted. It suits boats where the strainer needs to stay visible and easy to reach for routine cleaning rather than hidden deep in the plumbing run.

Key features

• 1/2 inch male NPT ports for threaded pump plumbing
• 40 mesh stainless steel screen for finer intake filtration
• Clear bowl lets you inspect the screen without opening the housing
• Screw-off housing makes screen cleaning quick while the strainer stays in line
• Installs on the inlet side of the pump and can be mounted in any position
• Helps keep rust, scale, and tank debris out of pump valves and internal parts
• Compact body at about 4 inches by 3 inches by 3-1/2 inches

Installation and setup

This strainer belongs between the tank or supply line and the pump inlet. For the easiest service access, place it where the bowl can be unscrewed and the screen can be rinsed without dismantling surrounding plumbing. On boats that see vibration and frequent washdowns, that usually means keeping it supported by the hose or pipe run and away from spots where the bowl would be hard to grip.

The 1/2 inch male NPT connection matters for fit. It suits systems that already use threaded fittings at the pump side, or installations where adapters are being used to join hose and threaded plumbing. Before ordering, confirm that your pump inlet side is set up for 1/2 inch NPT rather than hose barb connections.

Compatibility and fit

This is the finer 40 mesh version in the Pumpgard range. That makes it a strong match for freshwater pressure pumps and other cleaner water supply circuits where small particles can interfere with valves, faucets, shower heads, or spray nozzles. It is less about handling large debris and more about keeping finer contamination from moving farther into the system.

For boat owners replacing an older Pumpgard, the key checkpoints are the 1/2 inch male NPT port style, the compact footprint, and the 40 mesh screen grade. If your existing setup uses 1/2 inch hose barb ports instead of threaded ports, this is not the same connection style.

Maintenance and care

Routine cleaning is simple: shut off the water supply, relieve pressure if needed, unscrew the bowl, and rinse the stainless screen. Because the housing is clear, it is easier to spot buildup before flow starts dropping at the pump or fixtures.

This kind of strainer is a good match for owners who want a pump intake filter they can check quickly during regular system checks, winterizing, or after filling from a tank that may carry sediment. Keeping the screen clean helps the pump run with fewer interruptions and reduces the chance of debris reaching the valve set.
