Tube 8.3/8/9.5/9-32 TR218A
Product.Nr.: 990017397
Manufacturer: Novio
This high-quality inner tube in size 8.3/8/9.5/9-32 is designed for agricultural and industrial applications where reliability and pressure stability are essential. It is ideal for use in tractors, machinery and equipment with narrow tyres, ensuring a secure seal and even pressure distribution inside the tyre. Thanks to its multi-size design, the tube covers various tyre dimensions and thus offers high flexibility within the fleet.
Technical data
- Tube size: 8.3/8/9.5/9-32
- Inch size: 32 inch
- Also suitable for: 210/95-32 / 230/95-32

Valve TR218A – Features
- Valve design: Tubeless/tube valve for agricultural and industrial tyres, mostly used as a water/air valve
- Valve version: Straight metal valve with two-piece valve insert (core and upper part)
- Typical valve hole drilling: approx. 16 mm (for common agricultural and industrial steel rims)
- Valve length above rim: approx. 38–45 mm (depending on manufacturer)
- Closure: Hexagon lock nut and valve cap for secure fit and protection against dirt
- Medium: Suitable for air, often also for water filling (ballasting)
- Advantage: Enables easy filling and venting, even with liquid filling
Benefits and application
The 8.3/8/9.5/9-32 tube with TR218A valve is particularly suitable for narrow tractor tyres and similar special tyres. Thanks to its compatibility with tyre sizes 210/95-32 and 230/95-32, it can be used on various machines without having to keep a separate tube in stock for each size.
The robust construction ensures high pressure resistance and durability in daily use in the field, on the farm or on construction sites. The TR218A valve allows convenient air and water filling, which is particularly advantageous for tractors and work machines with ballast. This makes the tube a reliable solution for users who value operational safety, flexibility and easy maintenance.
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.
