Secoh JDK-80 Series Internal L-Tube
Genuine Secoh Replacement Internal L-Tube - JDK-80 Series
Keep your Secoh JDK-80 Air Pump running leak-free with a genuine replacement Internal L-Tube (Rubber Elbow Connector). Located inside the pump housing, this specialised rubber elbow connects the pump's internal discharge manifold to the outlet port, ensuring pressurised air is directed out of the pump without internal pressure loss.
Over years of continuous thermal cycling and operation in septic environments, internal rubber components can naturally become stiff, brittle, or cracked. Replacing a worn or perishing internal L-Tube ensures a tight seal, prevents internal pressure leaks, and keeps your aerated wastewater treatment system running at maximum efficiency.
Key Features & Benefits:
-
Genuine Secoh Component: Engineered to exact OEM factory dimensions to ensure an airtight seal and exact fit inside Secoh JDK series housing.
-
Flexible & Heat-Resistant Rubber: Formulated from high-grade elastomeric rubber designed to withstand internal pump operating temperatures and continuous vibration.
-
Prevents Air Leaks: Replaces cracked, loose, or hardened internal hoses that cause air pressure loss and reduced aeration.
-
Simple Maintenance: Direct push-fit replacement during routine chamber block or safety switch servicing.
Replacement Recommendations:
-
During Major Pump Rebuilds: Ideal to swap out when replacing your chamber blocks or diaphragms after long-term continuous use.
-
Visible Wear or Hardening: If the existing rubber hose feels brittle, cracked, loose, or sticky during inspection.
-
Pressure Drop / Air Loss: If your motor is running properly but overall air discharge pressure has dropped due to internal leakage.

Frequently asked questions
Is the JDK-80 suitable for my septic system?
The JDK-80 is designed for domestic aerobic wastewater systems that require approximately 80 litres per minute airflow. Always confirm your system’s airflow requirement before purchase.
How energy efficient is the JDK-80?
The Secoh JDK-80 consumes approximately 47–50 watts, similar to a small light bulb, making it one of the most efficient linear air pumps available.
Is the JDK-80 noisy?
No. With an operating noise level around 38–40 dB(A), it runs quietly and is suitable for residential installations.
Can the diaphragms be replaced?
Yes. JDK-80 Service kits are available and allow cost-effective maintenance without replacing the entire pump.
Is it weatherproof?
The unit is rain resistant but should be installed under cover and not exposed to direct sunlight or extreme weather.
