Product.Nr.: 990017162
Manufacturer: Novio
This high-quality inner tube in size 18.4/15-28 is designed for demanding industrial and agricultural applications. It is ideally suited for large-dimension tyres on machines and equipment where high load capacity and robust construction are required. Thanks to its suitable design, the tube is also compatible with tyres in size 600/65-28, offering flexible application options.
Technical data
- Tube size: 18.4/15-28
- Rim diameter: 28 inch
- Also suitable for: 600/65-28
- Valve type: TR218A
Valve-specific information (TR218A)
The TR218A valve is a common valve for high-volume tubes in the agricultural and industrial sector. It is designed for higher filling volumes and stable pressure retention.
Typical characteristics of the TR218A valve:
- Valve hole diameter: approx. 20.5 mm (for large-dimension valve holes in rims)
- Valve length: approx. 38–45 mm above rim surface (depending on manufacturer)
- Design: Straight valve with wide valve base for secure sealing
- Valve core: Standard car valve core (Schrader type) for easy inflation
- Suitable operating pressures: Designed for typical operating pressures of agricultural and industrial tyres (always observe the specifications of the tyre and machine manufacturer)
Benefits and application range
The 18.4/15-28 tube with TR218A valve is the right solution for large-dimension tyres on tractors, work machines, trailers and other equipment in the industrial and agricultural sector. Its robust construction ensures reliable airtightness and a stable fit inside the tyre, even under changing load and ground conditions.
Thanks to its compatibility with tyres in size 600/65-28, the tube can be used flexibly in different tyre combinations. The TR218A valve allows convenient inflation and deflation, which is particularly advantageous in professional use with frequent pressure adjustments. Overall, this tube offers a durable and economical solution for operations that rely on dependable tyres for their machinery.
Frequently asked questions about this product
The valve designation describes two things: the stem diameter — which must fit the hole in the rim — and the shape, i.e. straight or angled.
Only the bore matters for a proper fit: a valve fits perfectly only if its stem matches the bore in the rim. Whether it is straight or angled makes no difference — that is a question of accessibility.
An overview of the types:
| Type | Shape | Bore | typically used for |
|---|---|---|---|
| TR13 | straight, rubber | 11.5 mm | Car and trailer wheels |
| TR4 / TR6 | straight, short | 11.5 mm | Small wheels, garden tools |
| TR15 | straight, rubber | 16 mm | Agricultural machinery, tractor rims |
| TR87 | 90° angled | 11.5 mm | Small wheels, solid rims |
| JS8 (DIN 7777) | 90° angled, same as TR87 | 11.5 mm | small wheels, solid rims |
| JS2 | Approx. 70° angled | 11.5 mm | Industrial and small wheels |
| V3-02-7 (TR75) | 100° single-bend metal angle valve with screw-on base | 12.2 mm | Commercial vehicles, lorries, trailers, agricultural and industrial machinery such as forklift trucks |
| V3-06-3 | Triple-bend brass truck screw-on valve (90°/139°/139°) | 9.7 mm | 20-inch truck and trailer tubes (6.00-20 to 9.00-20), also 22.5-inch tube-type tyres |
| TR218A | Straight metal air-water valve, two-piece | 15.9–16 mm | High-volume tubular tyres for agricultural and industrial use, tractors |
V3-02-7 in detail: Also known as ETRTO V3.02.7 and US designation TR75. Dimensions: Horizontal leg length 22.5 mm, vertical leg length 71.5 mm, total height approx. 91 mm. The valve base is screwed on, not pressed in — this makes it significantly more robust than a rubber valve.
V3-06-3 in detail: Also known as ETRTO V3.06.3. Triple-bend brass screw-on truck valve: the first bend is 90°, the other two 139° each — this guides the filling end past the rim flange and keeps it accessible even with twin tyres and deep rim wells. Leg dimensions approx. 20.5 / 46 / 20.5 / 47.5 mm (approx. 135 mm developed length), rim hole 9.7 mm. The valve is fastened to the tube with a sealing washer and nut instead of being vulcanised in. In our range on the 20-inch tubes 6.00/6.50-20, 7.00/7.50-20, 8.25-20 and 9.00-20.
TR218A in detail — the valve for water ballast: What makes this type special is the option for liquid ballasting: the hose is partially filled with water to increase the vehicle’s weight and thus improve traction — a common practice with tractors.
- Design: straight, robust metal valve, usually in two parts. Unscrewing the inner CH3 valve insert creates an extra-large opening — allowing for quick filling with air or liquid.
- Rim bore: 15.9 to 16 mm (0.625 inches).
- Length: typically around 38 to 48 mm total height above the rim.
- Mounting: a rubber base approximately 80 mm in diameter for vulcanising onto the inner tube, plus a lock nut for secure attachment to the rim.
Reducing sleeves: A TR15 valve does not fit into an 11.5 mm bore. Conversely, there are sleeves that allow a TR13 valve to fit into a 16 mm bore.
Whether straight or angled is not a question of fit, but of accessibility: with closed rims or small wheels, it is often impossible to reach the valve with a pump using a straight valve — in which case an angled one is used.
Not sure which valve is fitted? A photo of the old valve is all we need to identify it. Choose from: inner tubes, bead tapes and valves.
