System-Purge WD-40 Lubricant Valve for Flushing Moisture from Hydraulic and Pneumatic Lines.
Product Description:
Address a critical maintenance need with our System-Purge Valve,
designed specifically for introducing moisture-displacing fluid
into hydraulic and pneumatic systems. This valve features a
proprietary quick-disconnect fitting that allows it to interface
directly with standard Schrader-type air valves or custom purge
ports. This enables technicians to inject a controlled amount of
moisture-displacing lubricant directly into an air or hydraulic
line, where it can vaporize and coat the entire internal system,
protecting it from corrosion and displacing residual water that
leads to component failure. The valve provides precise control over
the volume introduced, preventing over-application. This
specialized procedure is a game-changer for extending the life of
expensive pneumatic tools, hydraulic cylinders, and entire
compressed air systems, protecting them from the inside out. It is
a must-have for advanced preventive maintenance programs.
Bullet Points:
Features a quick-disconnect fitting for direct connection to Schrader valves and purge ports.
Allows for the introduction of moisture-displacing fluid directly into pneumatic and hydraulic systems.
Protects expensive internal components from corrosion and moisture damage.
Provides precise control over the volume of lubricant injected into the system.
Extends the service life of air tools, cylinders, and compressed air networks.
Specific Application Scenario: A fleet maintenance shop uses the valve to connect to the air brake system of a truck, injecting a precise amount of moisture-displacing fluid to protect the valves and chambers from internal rust.
Factory Production Floor: This valve is a hybrid assembly, combining a standard aerosol valve with a machined brass fitting. It is assembled on a dedicated, calibration-focused production line.
Packing and Transportation: Packaged in a high-value kit that includes the valve and several common adapter tips for different purge port types. Shipped in protective, foam-lined cases.
FAQ:
Q: How does this process protect a pneumatic system?
A: The moisture-displacing fluid is carried through the air lines
as a vapor, coating internal surfaces and neutralizing moisture,
which prevents rust and ice buildup in tools and valves.
Q: Is this safe for all pneumatic and hydraulic systems?
A: You must always consult the equipment manufacturer's guidelines.
While generally safe, some systems may have specific material
compatibility requirements.
Q: How much lubricant should I inject into a system?
A: This depends on the system volume. A general guideline is 1-2
ounces for a typical workshop air line. Our valve allows for very
controlled, small bursts to achieve this.
Q: Can I use the standard Multi-Use Product for this?
A: Yes, WD-40's moisture-displacing properties make it highly
effective for this purpose. For dedicated systems, WD-40
Specialist® Industrial Grade Corrosion Inhibitor is also an
excellent choice.
Q: Does this replace in-line air dryers and filters?
A: No, it is a complementary treatment. It adds an extra layer of
protection, especially for the downstream components that air
dryers cannot fully protect.
