Tubeless Sealant

Weldtite

£10.99

Weldtite Tubeless Sealant. Now with Rubber Shred for Proper Puncture Protection. Developed for Tubeless Tyres. Our Tubeless Sealant has just levelled up! Now featuring Rubber Shred; tiny 3mm nuggets of recycled tyres. These work a treat to improve sealing performance and installation. That means faster puncture repairs, without you even knowing, and more time sending it. Crafted with a water-based, anti-corrosive formula that’s CO₂ compatible, it’s as kind to your bike as it is to the planet. It’ll keep doing its job for up to 9 months in the tyre, a little less in hot conditions. No clogging,

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as WELDTITE PRODUCTS LIMITED, number 02558918. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Not yet checked.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
Not established. Many companies file a statement rather than naming a controlling shareholder.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
