Straight Pump Fitting – Ø13 mm Hose Barb (Inline Connector for Water Pump)

This straight pump fitting Ø13 mm (code 03822-5) allows you to connect a hose directly to your water pump with no bends – the perfect choice when you have ample space and want the simplest possible connection. The fitting is made of an engineering polymer (e.g., polyamide) that is corrosion-resistant and safe for potable water. Its design is inline, meaning the inlet and outlet are on the same axis, providing a straight-through flow path.

Specification: One end is a Ø13 mm hose barb intended for a hose with 13 mm inner diameter. The hose is secured over this barb using a clamp. The other end features a 1/2” male thread, which screws into a 1/2” female threaded port – typical for the outlet (or inlet) of many marine pumps. Essentially, this fitting acts as a replaceable straight pump barb. Some pumps have plastic barb fittings that thread in; if your pump has a threaded port, you can use this product as the straight barb connector.

When to choose a straight fitting:

• Installation with Adequate Space: If your pump is mounted with clear space around it and you don’t need to reroute the hose sideways, a straight fitting provides the most natural connection. For example, in a roomy engine compartment or under-sink area where the hose can run straight out from the pump without obstruction.
• Maximum Flow: Every turn or bend can slightly reduce pressure/flow due to friction. A straight connector introduces no additional curves – water flows directly, preserving the pump’s full capacity. This is important in long plumbing runs or when every bit of pressure counts (e.g., in showers that rely on gravity after the pump).
• Fewer Components: Using a straight fitting means one less potential failure point compared to a more complex setup with elbows or a looped hose. Fewer connections = lower risk of leaks.
• Universal Replacement: This fitting is a standard solution – it can replace an old or broken barb on a pump. If the pump’s original straight connector cracked or deteriorated, the 03822-5 restores functionality with minimal effort.

Installation: Attach the fitting to the pump by threading its 1/2” end into the pump’s female port. Use Teflon tape on the threads for a reliable seal. Hand-tighten, then snug it up with a wrench (plastic parts don’t require excessive force). Next, push your hose onto the barb as far as it will go. Secure it with a hose clamp to prevent it from slipping off under pressure. Ensure the hose can flex a little and isn’t rubbing on any sharp edges. If the hose is long, consider adding a support or guide so it doesn’t sag or kink unnecessarily.

With this straight fitting, your pump will be connected to the water system in a simple and efficient manner. This solution reduces potential failure points and maintains optimal flow – an excellent choice for anyone who values reliability and simplicity in marine equipment.
