Sensus 143-16-150-00 Diaphragm

Maintain precise pressure control and seating performance in commercial gas systems with the Sensus 143-16-150-00 12" diaphragm. Engineered specifically for Sensus 243-12-1 and 243-12-2 service regulators, this replacement regulator diaphragm is constructed from high-quality nylon fabric reinforced Buna-N elastomer to ensure sensitivity and durability across a broad temperature range of -20°F to 150°F. In large-capacity industrial meter sets and burner manifolds, the integrity of the 12-inch nominal diameter diaphragm is critical for preventing outlet pressure overloads and ensuring accurate lock-up. When performing a regulator repair, technicians must clean the diaphragm pan with a suitable solvent and apply a compatible rubber-based adhesive to the pan before securing the new Sensus 143-16-150-00. This genuine OEM component supports the consistent regulation of natural gas, LPG vapor, air, and other non-corrosive inert gases, keeping industrial boilers, furnaces, and kilns operational without unexpected pressure fluctuations or venting issues.

• Precise Compatibility: Custom-fit for the Sensus 243-12 series, ensuring accurate response to downstream demand.
• Industrial Durability: Reinforced 12-inch elastomer design resists fatigue and maintains flexibility in fluctuating outdoor temperatures.
• Versatile Media Handling: Optimized for use with natural gas, propane, nitrogen, and dry CO2 in commercial applications.
• System Safety: Enhances the performance of internal relief (IRV) models by providing consistent torque response at the 150 in-lbs bolt specification.

Which regulator models use the Sensus 143-16-150-00?
This 12-inch diaphragm is designed for the Sensus 243-12-1 (standard) and 243-12-2 (internal relief) models. It is larger than the 8-inch diaphragms used in the 243-8 series and is not interchangeable between the two sizes.

What is the temperature rating for this replacement part?
The diaphragm is rated for flowing temperatures ranging from -20°F to 150°F, making it suitable for most standard industrial and commercial installations.

Can this diaphragm be used for corrosive gas service?
Standard Buna-N construction is optimized for non-corrosive gases like natural gas and nitrogen. For specialized corrosive applications, specific material compatibility must be verified with technical documentation.
