Tube 18.4/15-34 Valve TR218A
Product.Nr.: 990017164
Manufacturer: Novio
This high-quality tube in size 18.4/15-34 is designed for use in agricultural and industrial applications. It is ideal for large-dimension tyres where high load capacity, stability and reliable air pressure are required. Thanks to the robust TR218A valve type, the tube is specifically designed for use in tractors, work machines and similar vehicles with high-volume tyres. The compatible tyre sizes 460/85-34, 520/70-34 and 600/55-34 allow flexible use in various machines and application scenarios.

- Media: Air, in many cases also water/antifreeze for ballasting
Advantages and application range
The 18.4/15-34 tube with TR218A valve is ideal for professional use in agriculture and industry. By being designed for multiple tyre sizes (460/85-34, 520/70-34, 600/55-34), it covers a wide range of machine types, such as tractors, tillage equipment, harvesting machines or municipal service vehicles.
The robust TR218A valve ensures secure seating in the rim, high operating pressure and convenient filling and deflation – even with water-filled tyres. This makes the tube particularly suitable for applications where high loads, changing ground conditions and long operating times are part of everyday work. Overall, this tube offers a reliable, durable solution for demanding professional use.
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.
