Bicycle Vacuum Inner Tube Valve Core Aluminum Alloy Copper 40mm to 120mm for Road and Mountain Bike Tyres with Transparent Washer Sealing Ring Options
Bicycle Vacuum Inner Tube Valve Core 40mm to 120mm Aluminium Copper

This bicycle vacuum inner tube valve core is a metal replacement part for removable valve cores. It is offered in 40mm, 60mm, 80mm, 100mm and 120mm lengths, giving you a way to match different valve stem depths. The core is built with an aluminium cover, a copper core and an alloy bar. Colour choices include black, blue, orange and red, so the valve core can sit neatly with different rim and valve stem finishes. Pack options cover a single valve core, a pair of suit 1, or a pair of suit 2. The pair options add transparent washers and, on suit 2, sealing rings and concave-convex washers. This makes the listing useful for cyclists who keep spare valve cores for vacuum tyre setups and want a straightforward replacement part.
Features and Construction

The valve core is made from metal with an aluminium cover and copper core. It is a small component intended for vacuum inner tube and tyre valve use. The available length range is broad, from 40mm up to 120mm, which helps you choose a core that reaches correctly through the valve stem. No pressure rating, torque setting or inflation limit is provided in the source data, so fit and inflation should follow your existing rim and valve manufacturer guidance.
Material and Build
The stated materials are aluminium, copper, alloy and metal. The aluminium cover forms the outer part of the valve core, while the copper core and alloy bar make up the internal structure. These materials are common in valve core construction, and the metal build is intended for a removable valve core application. The product does not carry any stated certification, durability rating or corrosion-resistance test result in the source text, so no such claim is made here.
Size and Practical Fit
Length options are 40mm, 60mm, 80mm, 100mm and 120mm. The correct choice depends on the depth of your valve stem and rim. A shorter core suits shallower valve stems, while a longer core is intended for deeper valve stems. The listing does not state which bicycle types, rim profiles or tyre systems are compatible beyond the vacuum inner tube reference. Please compare the stated length with your existing valve core before ordering.
Uses and Placement

This valve core is used in bicycle vacuum inner tubes and tyres that accept a removable valve core. It can be kept as a spare for puncture repairs, tyre changes or routine valve maintenance. The pack options make it possible to order a single replacement or a pair with additional washers and sealing rings. Because the source data does not specify road, mountain, gravel or hybrid compatibility, the length and valve stem type remain the main selection points.
Event or Professional Use
For bike shops, workshops or race support, a small stock of 40mm to 120mm valve cores can cover several valve stem depths. The pair of suit 1 and pair of suit 2 options include transparent washers and, on suit 2, sealing rings and concave-convex washers. These extra parts can be useful when replacing a valve core and the existing washer or seal has been removed. No professional certification or workshop rating is stated in the source data.
Everyday Home Use
For home mechanics, the single pack offers one valve core for a direct replacement. The pair options give two valve cores and additional washer or sealing ring parts. This can be practical if you maintain more than one bicycle or prefer to keep a spare. The product is small and metal, so store it in a dry place with the washers and sealing rings until needed. No shelf life or storage temperature is stated in the source text.
Benefits and Buying Value

The main buying value is the choice of length, colour and pack contents. The aluminium cover, copper core and alloy bar construction are stated facts, and the 40mm to 120mm range covers several common valve stem lengths. The availability of a single pack and two pair options means you can order only what you need for a replacement or a spare. No price comparison, discount claim or long-term performance promise is made because the source data does not provide those details.
Reuse and Low Maintenance
The valve core is a replaceable metal component, so it can be swapped when a valve core is damaged or removed. The supplied transparent washers, sealing rings and concave-convex washers on the applicable pack options allow you to refresh the sealing parts at the same time. The source data does not give cleaning instructions, lubrication guidance or a replacement interval. A practical approach is to inspect the valve core and washers during tyre or inner tube service and replace them when they show wear.
Why Choose This Product
Choose this valve core if you need a replacement in a specific length and colour. The range includes black, blue, orange and red, and lengths from 40mm to 120mm. The pack choices let you buy one valve core or a pair with transparent washers and black gadgets, or a pair with transparent black washers, sealing rings and concave-convex washers. The listing does not claim compatibility with every bicycle or valve system, so checking the length and pack contents against your current setup is the safest way to order.
