Spirax-Sarco 58129 Float Mech Kit

Ensure your steam system maintains peak efficiency with the Spirax-Sarco 58129 Float Mech Kit, specifically engineered for 1 1/2" FT-15 Float and Thermostatic Steam Traps. This field-serviceable kit is a critical component for technicians performing standard steam trap maintenance or clearing condensate blockages that threaten heat transfer. Manufactured with high-grade stainless steel internals, the 58129 kit resists the corrosive effects of condensate and handles the rigors of saturated steam service up to the designated 15 PSI operating limit. By replacing a water-logged or distorted ball float, you restore the trap’s ability to modulate flow and discharge condensate continuously at steam temperature. This replacement float mechanism is designed for an exact fit, allowing for on-line servicing without disturbing existing piping. Rely on this Spirax-Sarco OEM part to prevent steam loss and protect your downstream equipment from the damaging effects of water hammer and thermal shock.

Key Benefits

• Precision Condensate Control: Restores the modulating action of the mechanical ball float for continuous discharge without live steam loss.
• Industrial-Grade Durability: Constructed from stainless steel to withstand demanding environments and provide long-term reliability.
• Simplified Maintenance: Designed for rapid in-line replacement, reducing system downtime during scheduled steam trap repairs.
• Universal Compatibility: Fits 1 1/2" Spirax-Sarco FT-15 series traps and select FTB models, ensuring a precise seal and mechanical alignment.

Common Questions

How do I know if my FT-15 float needs replacement?
If the trap fails to discharge condensate or you hear the distinct clanging of a collapsed float caused by water hammer, a new float mechanism is required. A water-logged float will stay at the bottom of the trap, causing it to fail closed.

Can I install the 58129 kit without removing the trap from the pipeline?
Yes, Spirax-Sarco F&T traps are designed for easy maintenance. After isolating the trap from the supply and return lines, the cover can be removed to replace the internals while the body remains in the piping.

Is a gasket included with the 58129 float kit?
This kit typically consists of the spherical float, washer, and screw. It is technical best practice to install a new Spirax-Sarco gasket kit simultaneously to ensure a leak-free seal upon reassembly.
