Product.Nr.: 990017034
Manufacturer: Novio
This high-quality 11.2/10-20 tube with valve type TR218A is designed for use in agricultural and industrial applications. It is ideal for tractors, work machines and equipment used in gardening and municipal operations where robust and reliable tube solutions are required. Thanks to its matched dimensions, the tube can be used not only for size 11.2/10-20, but also for alternative tyre sizes.
Technical data
- Tube size: 11.2/10-20
- Rim size: 20 inch
- Also suitable for: 280/85-20, 320/70-20
- Valve type: TR218A
Valve type TR218A – technical features:
- Design: Straight, large-dimension tube valve for agricultural and industrial tyres
- Valve hole (rim hole): approx. 16 mm (standard for TR218A)
- Valve length: approx. 38–45 mm above rim surface (slight variations depending on manufacturer)
- Construction: Two-piece metal valve with replaceable valve core and locknut for secure fixing in the rim
- Suitable for: Tube systems with higher inflation pressure in agricultural and industrial use
- Sealing: Rubber base with metal valve that fits tightly in the rim hole and ensures reliable air retention
Benefits and applications
This tube is specially developed for tyres in size 11.2/10-20, but can also be used in tyres of sizes 280/85-20 and 320/70-20 thanks to its compatibility. This provides high flexibility for the tyres of tractors, yard loaders, municipal and work machines.
The TR218A valve type is widely used in the agricultural and industrial sectors and allows convenient inflation and deflation, even at higher pressures. The robust valve design ensures a secure connection to the rim and minimises air loss.
Typical fields of application are:
- Agricultural machinery (e.g. tractors, implements)
- Municipal and garden machinery
- Industrial commercial vehicles and work equipment
Thanks to its solid design and standardised valve type, this tube is a reliable solution for users who value durability, easy handling and high operational safety.
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.
