Tube 16.9/14-34 TR218A
Product.Nr.: 990017142
Manufacturer: Novio
This robust inner tube in size 16.9/14-34 is designed for use in agricultural and industrial applications. It is ideal for vehicles and machinery that must operate reliably under varying ground and operating conditions. Thanks to its solid construction and the proven TR218A valve, the tube offers reliable air tightness and allows convenient inflation and deflation, even with high-volume tyres.
Technical data
- Tube size: 16.9/14-34
- Rim diameter: 34 inch
- Also suitable for tyre sizes: 420/85-34, 480/70-34, 540/65-34
- Valve type: TR218A
Valve type TR218A – technical details
The TR218A valve is a special tube valve for high-volume agricultural and industrial tyres. It is designed for high air flow rates and enables fast inflation and deflation.
Typical technical characteristics of the TR218A valve:
- Valve hole diameter: approx. 16 mm (suitable for larger valve holes in tractor and industrial machine rims)
- Valve length: usually approx. 38–45 mm above rim surface (depending on manufacturer)
- Design: straight valve with wide rubber base for secure sealing in the tube
- Valve core: replaceable core for easy maintenance and quick deflation
- Cap: metal cap for protection against dirt, moisture and damage
Benefits and application range
This tube is specially designed for use in high-volume tyres in agricultural and industrial environments. It fits a wide range of common tyre sizes (420/85-34, 480/70-34, 540/65-34), providing high flexibility in use. The robust construction ensures good dimensional stability and reliable sealing, even under high loads and varying air pressures.
Typical applications include tractors, agricultural trailers, soil cultivation equipment and various industrial machines. The TR218A valve allows rapid adjustment of tyre pressure, which is particularly advantageous in the field, off-road or during transport work. Overall, this tube offers a durable, reliable solution for professional users who value operational safety and easy handling.
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.
