ST shengtuo TR501 Brass Valve Stems 10-Pack — 0.748" (19mm) Hole, 1.65" Length, EPDM Sealed

ST shengtuo TR501 brass valve stems are a 10-piece set of clamp-style tire valves made for commercial vehicles, sized for 0.748" valve holes and built to withstand heavy-duty use.

These TR501 valve stems combine a brass body with EPDM sealing components to deliver a robust sealing solution for air and liquid systems on trucks, buses and other large vehicles. Sold in boxes of ten, they are designed for straightforward installation in standard 0.748" valve openings (approx. 19mm) and offer a durable alternative to rubber-only valves when exposure to fuel, oil or frequent servicing is expected.

How do these TR501 stems hold up under heavy use?

The TR501 stems use a brass construction that resists corrosion and deformation better than many standard valves, while EPDM seals maintain flexibility across a wide temperature range. That combination reduces replacement frequency in fleet applications and is tolerant of contact with common vehicle fluids.

• Brass body for improved mechanical strength and corrosion resistance
• EPDM sealing parts for chemical and temperature resilience
• Clamp-style design secures the stem to the wheel assembly for leak prevention
• Intended for repeated service and long-term fleet use

Will these valves fit my vehicle’s wheel valve hole?

The TR501 valve stems are engineered for valve holes measuring 0.748 inches in diameter. That size matches many commercial wheels and rims; measure your existing valve hole if unsure. The listed 1.65" length provides adequate reach for most rim configurations but always compare to your current stems.

• Valve hole compatibility: 0.748 inches (approximately 19 mm)
• Stem length: 1.65 inches to clear wheel thicknesses
• Clamp-style mounting works with standard heavy-duty rims
• Sold in a 10-piece box for multiple wheel installations or spares

Can these valve stems handle air and liquid applications?

Yes — the TR501 is designed as a clamp-style valve suitable for both air and certain liquid lines commonly found in commercial vehicle systems. The EPDM seals provide reliable sealing for compressed air and many non-corrosive liquids, though always confirm chemical compatibility for specialty fluids.

• Suitable for compressed air systems on commercial vehicles
• EPDM seals compatible with many vehicle fluids (check specifics for unusual chemicals)
• Clamp mount ensures a tight seal under pressure
• Appropriate for trucks, buses and heavy equipment with matching valve holes

How does packaging and support make maintenance easier?

The valve stems come packaged in groups of ten, which is practical for fleet servicing or keeping spares on hand for roadside repairs. ST shengtuo provides customer support to assist with fitment questions and post-purchase concerns, helping reduce downtime during maintenance cycles.

• Box of 10 valves for efficient fleet purchasing
• Keeps multiple spares available for quick replacements
• Customer support from ST shengtuo for fitment and troubleshooting
• Cost-effective option versus single-piece purchases

Who is this for: The ST shengtuo TR501 10-piece valve stem set is aimed at fleet managers, commercial vehicle repair shops and individual owners of trucks or buses who need reliable, long-lasting valve stems that fit a 0.748" valve hole. If you maintain heavy-duty wheels, want brass durability, and prefer buying spares in bulk for faster service, these valve stems are a practical choice.
