A trading company, and clear about it.
Sealpart is the trading name of Guangzhou Sealpart Trading Co., Ltd. We buy from a mould shop in Shenzhen and sell to distributors and repair shops in Europe. We do not own a factory, and we are not going to pretend otherwise in the About page — it is the first thing a buyer checks.
What that means in practice
One person who answers, instead of a department that routes.
A distributor with 35,000 lines in stock will beat us on breadth every time. What a small buyer usually needs is narrower than that: someone who can confirm whether a specific size exists, in the compound that suits the fluid, and put it on a plane this week.
That is the whole proposition. We hold no warehouse of our own; goods are drawn from the mould shop's finished stock against your order. It is why we can quote across 2,500 sizes without asking you to take a carton of each — and it is also why we sometimes have to say no.
Our production partner's finished-goods warehouse, Shenzhen. We do not hold this stock ourselves — we draw from it against your order.

Working with us
Four things we will not do.
We will not call ourselves a manufacturer
Buyers check. A trading company that claims a factory loses the account the moment someone asks how many curing presses they run.
We will not substitute a near size
If you ask for AS568-214 and we only hold 31.5 × 3.55 metric, we say so. Shipping the metric ring and hoping is how a supplier loses a customer for good.
We will not quote a price we cannot hold
Rubber moves with compound prices. Our quotations state a validity period, and we honour it inside that window rather than re-pricing after you have quoted your own customer.
We will not sell you a compound that is wrong for the fluid
NBR into phosphate-ester will swell and leak, and it will happen after you have fitted it. We would rather lose the order at the quotation stage.
Start with one size.
The quickest way to judge a new supplier is a small order that arrives correct. Send a dimension and see what comes back.
