Weil McLain 590-317-630 Hose
The Weil McLain 590-317-630 Pressure Switch Hose is a critical component for maintaining the pneumatic integrity of Weil McLain HE, VHE, and HE-II series boilers. Measuring 12 inches in length with a 1/8-inch I.D., this white pressure differential switch tubing is engineered to transmit precise air pressure readings from the blower or heat exchanger to the boiler pressure switch. In high-efficiency hydronic systems, accurate signal transmission is vital for proving the inducer fan operation and ensuring the safe initiation of the ignition sequence.
Constructed from high-grade, flexible elastomer, this OEM Weil McLain replacement part resists the thermal cycling and chemical exposure common within the boiler cabinet. A compromised or cracked sensing tube can lead to intermittent pressure switch faults, "no-heat" calls, or "pressure switch failed to close" errors. For contractors performing preventative maintenance or diagnosing combustion issues, replacing brittle 1/8-inch tubing ensures the differential pressure switch receives the stable signal required for optimal burner modulation and safety compliance.
Key Benefits:- System Precision: Ensures 100% accurate signal transmission between the sensing port and the differential pressure switch.
- OEM Fitment: Pre-cut 12-inch length and 1/8-inch I.D. provide a secure, leak-proof seal on standard Weil McLain barb connectors.
- Series Compatibility: Specifically designed for Weil McLain HE, VHE, and HE-II gas-fired water boilers.
- High-Contrast Color: White tubing allows for quick visual inspection of blockages, moisture buildup, or cracks during service calls.
- Can I use universal silicone tubing instead of this OEM hose? While universal tubing exists, this Weil McLain 590-317-630 hose is specifically rated for the internal temperatures and pressure tolerances of the HE series, preventing premature failure or collapsing under vacuum.
- What causes these hoses to fail? Over time, heat exposure causes the tubing to become brittle or "pinch" at the barb, which leads to signal loss and system lockouts.
- Does this hose include the barb fittings? No, this is the 12-inch pressure switch tubing only; ensure your existing barbs are clean and free of debris during installation.
