Professional 4mm Plastic Airline Fittings and Connectors

Our 4mm Plastic Airline Fittings and Connectors are the industry standard for koi pond aeration. Whether you are a hobbyist or a professional, these connectors provide a reliable way to manage your airflow.

Consequently, they are completely safe for your fish and won’t leach chemicals into the water.

Why Choose Our Airline Connectors?

Aeration is vital for a healthy pond environment. However, air leaks can reduce the efficiency of your expensive air pumps. By using our 4mm Plastic Airline Fittings and Connectors, you create a secure, airtight seal. This ensures that every bit of oxygen reaches your air stones or diffusers. Furthermore, we offer a variety of shapes including T-pieces, elbows, and straight joiners to suit any pipework layout.

• Standard Sizing: Designed perfectly for all 4mm ID (Internal Diameter) silicone and PVC hoses.
• UV Resistant: These 4mm Plastic Airline Fittings and Connectors will not become brittle when exposed to sunlight or pond lighting.
• Smooth Bore: The internal design reduces air friction. As a result, your pump runs more efficiently with less back-pressure.

Installation and Compatibility

First, ensure your airline is cut squarely for the best fit. Next, simply push the hose over the ribbed barb of the 4mm Plastic Airline Fittings and Connectors. If the fit is tight, you can dip the end of the hose in warm water. This makes the installation much easier. In addition, these fittings work perfectly with our airline manifolds and taps for a complete professional setup.
