Tube 23.1-34 TR218A
Product.Nr.: 990017234
Manufacturer: Novio
This tube in size 23.1-34 is designed for heavy-duty use in agriculture, industry and horticulture. It is ideal for large drive and traction tyres and ensures reliable air pressure build-up even under high loads. Thanks to the TR218A valve type, safe and convenient inflation and deflation of the tyre is guaranteed. The tube is also suitable for tyre size 650/75-34, thus covering common dimensions in professional applications.
Technical data
- Tube size: 23.1-34
- Rim diameter: 34 inch
- also suitable for: 650/75-34
- Valve type: TR218A
Valve TR218A – technical details
- Valve design: Straight, large-dimension tube valve for agricultural and industrial tyres
- Typical valve hole diameter: approx. 16 mm (for large bore in tractor and machinery rims)
- Valve length: usually approx. 38–45 mm above rim surface (depending on manufacturer)
- Valve core: replaceable insert for easy servicing and pressure adjustment
- Sealing system: rubber base with metal valve for high pressure stability and secure sealing in the rim hole
- Operating pressure range: designed for the operating pressures commonly used in agricultural and industrial tyres
Benefits and application
This tube is specially designed for large-dimension tyres in size 23.1-34 as well as the alternative dimension 650/75-34. It is suitable for tractors, agricultural trailers, work platforms, earthmoving machinery and other heavy equipment where high load capacities and changing ground conditions occur.
The TR218A valve enables fast inflation and deflation, which is particularly advantageous when tyre pressure needs to be adjusted frequently between field and road use. The robust construction ensures durability, reduces downtime and supports stable, even running of the tyre on a wide variety of surfaces.
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.
