The Vaillant 0020143495 Pressure Gauge is a genuine replacement instrument designed to display the water pressure within your boiler’s central heating system. Clear and accurate pressure readings are essential for maintaining correct system performance, preventing low-pressure faults and ensuring the boiler operates within safe parameters. A faulty or unreadable gauge can make it difficult to monitor system health, potentially leading to inefficiencies or boiler lockouts.

This pressure gauge is compatible with Vaillant EcoTEC VU and VU series boilers that specify part number 0020143495 in their technical documentation. To ensure correct fitment and reliable readings, always verify the part number on your existing gauge or consult your boiler’s service information before installation, as gauge designs and scales vary between models.

Supplied ready for direct replacement, the 0020143495 Pressure Gauge installs into the boiler’s designated pressure port and integrates with the system’s plumbing when fitted by a qualified engineer. Choosing this genuine Vaillant component helps restore accurate water pressure monitoring, supports effective system maintenance and contributes to dependable heating performance in compatible EcoTEC VU/VU boilers.
