Spirax-Sarco 58128 Gasket

The Spirax-Sarco 58128 is an industrial-grade 2" replacement gasket specifically engineered for high-performance sealing in FA series and FT series float and thermostatic steam traps. This graphite cover gasket is critical for restoring system integrity during scheduled maintenance or rebuilds of 2-inch Spirax Sarco FT-15, FT-125, FA-30, and FA-150 units. Designed to withstand the thermal cycling and high-pressure demands of localized heating and process steam applications, this component ensures a leak-tight interface between the trap body and the cover, preventing live steam loss and maintaining energy efficiency across the condensate return loop.

For technicians servicing large-scale mechanical rooms, the 58128 gasket provides a precise fit that eliminates the need for messy liquid sealants. Its durable graphite construction is chemically resistant and rated for the elevated temperatures typically found in saturated steam systems. By replacing the cover gasket every time the trap is opened for inspection of the float mechanism or thermostatic air vent, you prevent nuisance leaks and protect internal components from atmospheric corrosion. This part is a standard requirement for maintaining ASME-compliant steam systems and ensuring the float and thermostatic trap operates at peak discharge capacity without bypass leakage.

• Direct OEM Replacement: Matches exact dimensional specifications for 2-inch FT and FA series steam trap covers.
• High-Temperature Resilience: Engineered with reinforced graphite to maintain a positive seal under fluctuating steam pressures.
• Operational Efficiency: Eliminates bypass leaks to ensure the condensate removal process remains optimized.
• Ease of Installation: Designed for rapid field replacement during routine steam trap surveys and repairs.

• Which steam trap models are compatible with the 58128? This gasket is specifically for 2" NPT or flanged FT-15, FT-30, FT-75, FT-125 and FA series traps.
• Is this an individual gasket or a kit? While listed under part 58128, this is typically provided as a single replacement cover gasket for 2" trap bodies.
• Can this gasket be reused after the cover is removed? No, professional best practice dictates replacing the cover gasket every time the trap is disassembled to ensure a reliable seal upon re-torquing the bolts.
