Kyotechs' official catalogue carries a Seal Kits category (with rubber parts alongside), and its Alibaba store groups seals as their own line. The documented extract is heavily Volvo — cylinder kits for Volvo wheel loaders alongside the excavator kit — and each listing is reproduced here under its documented application. Seal kits are cylinder-specific: boom, bucket, arm, tilt and steering cylinders take different kits even on one machine. The companion guide, how to choose an excavator cylinder seal kit, walks through the identification steps.

Ordering the Right Kit
- Kit number or cylinder number first. A kit is matched to a cylinder, and the cylinder number is stamped on the barrel or found in the machine's parts book.
- Machine model and cylinder position. "Seal kit for an EC240" is not enough — boom, arm and bucket kits differ.
- One cylinder or the whole machine? Shops often reseal all cylinders on an older machine while it is apart; say so and the reply prices the set.
- Rod and bore condition. A kit cannot fix a scored rod or a worn bore — if the chrome is damaged, read the cylinder page before ordering seals into a leaking cylinder.
Delivery and preparation times are confirmed for your order in the enquiry reply, in writing and before payment: the reply states the times, the packing and the shipping method that apply to your exact part number. Times are confirmed per order rather than published as a general figure, because they follow the listing, the quantity and the destination.
Frequently Asked Questions
Are these kits for excavators or wheel loaders?
Both appear in the documented catalogue, and each row above states its application honestly — the excavator bucket kit is 14589133 for the Volvo EC240; the loader kits serve the Volvo L-series machines listed. Kits for other excavator cylinders are confirmed by cylinder number.
What is inside a seal kit?
The seals, wipers, wear rings and O-rings for one cylinder, as listed for that kit number. The guide on this site explains how kits are composed and how to verify contents before assembly.
Do the parts carry a warranty?
Warranty terms are confirmed in writing for each order before payment. Kyotechs' own FAQ states that most parts are backed by a warranty against manufacturing defects; ask for the term that applies to your listing when you enquire.
Shelf Life and Storage, Briefly
Seal kits are perishable stock. Elastomers age with heat, ozone and time, which is why a kit is bought for a job in hand rather than as shelf insurance, and why the reply confirms the listing's current stock rather than a years-old shelf item. Store a kit flat, sealed, away from sunlight and solvents until the day of fitting, and fit it in one clean session: a cylinder opened on Monday and sealed on Friday collects the dust that shortens the new seals' life. These are small disciplines, but reseal work is where small disciplines are the whole job.
