Parker 76727 Repair Kit

The Parker 76727 Repair Kit is a field-standard maintenance solution engineered for GP300 and GP400 series general-purpose solenoid valves. Specifically designed for 1/2-inch configurations, including the Parker 58-1018 water solenoid valve, this kit contains the critical components needed to restore seal integrity and valve response. Every Skinner valve repair kit includes a high-grade rubber diaphragm—offering superior elastic response compared to Teflon alternatives—alongside a precision-wound spring assembly and a diaphragm cartridge with an integrated mesh strainer to prevent particulate contamination of the seat.

For technicians servicing Cleveland steam equipment or commercial fluid control systems, the 76727 Parker repair kit ensures reliable performance under fluctuating temperatures and chemical exposure. Replacing the plunger and O-ring during routine maintenance intervals prevents common failure modes such as internal leakage and slow actuation. This kit provides a drop-in OEM-spec solution to maintain the 3.35 Cv flow rating of Parker Hannifin GP400 series valves without the high cost of a total unit replacement.

• Optimized Compatibility: Designed specifically for Parker GP300/GP400 series 1/2-inch valves and C-157 solenoid applications.
• Enhanced Filtration: Includes a factory-installed mesh strainer within the diaphragm cartridge to protect the valve orifice from debris.
• Robust Seal Design: The rubber diaphragm ensures a positive seal for water and light fluid applications where leak prevention is critical.
• Complete Service Set: Contains the plunger, spring assembly, and O-ring, streamlining the rebuild process for field contractors.

Is the diaphragm in this kit compatible with high-heat steam?
This kit utilizes a rubber diaphragm rather than Teflon, making it ideal for standard water and fluid control in series like the GP400, but always verify hardware temperature limits for specific steam applications.

Will this work with 3/8-inch Parker valves?
Yes, the 76727 kit is the designated repair solution for both the GP300 (3/8") and GP400 (1/2") valve bodies.

Does this kit include the solenoid coil?
No, this is a mechanical rebuild kit containing internal wear parts like the plunger and diaphragm; coils such as the G23-120 must be sourced separately if electrical failure is detected.
