TR501-OV Brass Clamp-In Truck Valve Stem 1.5" Oval Hole - 1 Valve
The TR501-OV is a 1.5" straight brass clamp-in truck tire valve stem designed specifically for wheels with an oval valve hole measuring 0.625" x 0.875". Rated to 150 PSI max cold pressure, it is dimensionally identical to the standard TR501 in body diameter and thread configuration, but features an oval base flange that seals correctly against elongated valve hole geometry.
If your commercial wheel has an oval valve opening rather than a round one, the TR501-OV is the correct replacement. Using a round-base stem on an oval hole will result in an improper seal and potential air loss.
Specifications
- Height: 1.5" straight profile
- Valve Hole: Oval 0.625" x 0.875"
- Max Cold Pressure: 150 PSI
- Material: Brass body with O-ring seal
- Cross-Reference: TR501-OV
Frequently Asked Questions
How do I know if my wheel needs the TR501-OV versus the standard TR501?
Measure the valve hole in your wheel. If it is circular and approximately 0.625" in diameter, use the TR501. If the hole is elongated (oval) and measures approximately 0.625" x 0.875", use the TR501-OV. Using the wrong base geometry will result in a poor seal and air leakage.
What vehicles use oval valve holes?
Oval valve holes are found on certain commercial truck and trailer wheels, particularly from some European manufacturers and older domestic designs. Check your wheel specification or measure the existing hole before ordering.
What is the maximum pressure rating for the TR501-OV?
The TR501-OV is rated to 150 PSI max cold pressure, the same as the standard TR501.
What are the cross-reference part numbers for the TR501-OV?
TR501-OV is the standard industry cross-reference designation for this valve stem. Verify against your wheel spec if you are sourcing as a direct replacement.
Can I use the TR501-OV on a round valve hole wheel?
No. The oval base is designed to seal against an oval hole. Installing it on a round valve hole will not produce a proper seal. Use the standard TR501 for round 0.625" valve holes.
