Home improvement hardware that supplies a robust manual inflation point for air-spring suspension systems and 1/4-inch air-line tubing. Secure, leak-resistant connections make topping up and adjusting air bags straightforward and less stressful for technicians and owners. Is the CheeMuii Schrader Inflation Valve the durable, easy-to-use inflation solution worth fitting to your rig?
⚡ At a Glance
- • Sealing Performance: Tight, leak-resistant sealing under pressure thanks to brass construction and precision CNC threads
- • Best for: Owners and technicians of trailers, tractors and semi trucks using air spring suspension
- • Not ideal for: Applications that require integrated digital tyre-pressure monitoring or automated inflation systems
DOT-approved valves handle pressures up to 200PSI and mate with 1/4-inch OD air-line tubing. Push-to-connect PTC design enables fast hose attachment and a protective cap keeps mud and dirt away.
Reliable high-pressure sealing - Thanks to DOT-approved brass construction
Brass bodies include CNC-machined threads that produce accurate mating surfaces rated to operate at pressures up to 200PSI according to the certification. Precise threading reduces micro-gaps where air can leak under load.
Secure metal-to-metal contact and precise threads reduce leak risk during heavy-duty use, giving confidence when inflating or adjusting air springs.
Quick hose connection - With PTC push-to-connect design
The push-to-connect mechanism uses a release button on the DOT side that allows a 1/4-inch air pipe to be inserted and locked without tools. Pressing the same button disengages the grip for simple removal.
Tool-free attachment and removal speeds up routine inflation, roadside adjustments and workshop work, saving time for fleet maintenance.
Cleaner, longer service life - With protective sealing covers
A threaded protective cap seals the valve and its threads to prevent mud and dirt ingress, maintaining the sealing surfaces and internal components. Reduced contamination lessens wear on threads and seals.
Less debris around the valve means fewer service interventions and a longer usable life for inflation points on suspension bags.
