Tube 8x1 1/4 DIN 7768 90/30 valve
Product.Nr.: 990017406
Manufacturer: Novio
This tube in size 8x1 1/4 is designed for narrow wheels and tyres in industrial and garden applications. It is particularly suitable where a compact, lightweight wheel with reliable air sealing is required, such as on hand trucks, platform trolleys, smaller machines or equipment used in gardening and landscaping. The DIN 7768 90/30 valve ensures safe inflation and a stable fit in the valve hole, providing reliable operation in everyday use.
Technical data
- Tube size: 8x1 1/4
- Inch size: inch
- Valve type: DIN 7768 90/30
Valve-specific data (DIN 7768 90/30)
- Standard: DIN 7768
- Design: right-angled valve (approx. 90°) with offset position (30°) for optimal accessibility
- Application range: tube valve for small wheels and narrow rims in low to standard pressure range
- Valve hole drilling: designed for standard rim hole of approx. 8.3–8.5 mm
- Valve length: medium design, suitable for narrow rims and small tyre diameters
- Valve seat: firm seat with seal in the rim hole for secure air sealing
- Inflation: suitable for standard compressed-air devices and pumps with matching connection (e.g. compressor or hand pump)
Benefits and application range
This tube is ideal for smaller wheels where precise fit and good air tightness are required. The 8x1 1/4 size allows use in compact wheels on hand trucks, sack trucks, light transport equipment or special machines in gardening and industrial applications.
The DIN 7768 90/30 valve makes inflation easier even in confined spaces, as the angled design improves access to the valve cap. Thanks to its standardised design, the valve fits common rim holes and ensures reliable sealing. The tube is therefore a suitable solution for users who need a robust, low-maintenance and compatible spare part for their small wheels.
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.
