SILCA LIMITED WARRANTY
Parts covered by SILCA Limited Warranty are considered to be subject to wear through normal use or are consumable subject to degradation through the course of their daily use. SILCA guarantees them free from manufacturer defects for 2 years.
So we've always noticed how really expensive tubulars had such nice valve cores with smooth edges and high quality seals that resisted sticking. When we started developing SILCA Tubeless valve stems, we set out to find the best cores, and realized that only a handful of companies make them globally. After a lot of phone calls, emails and discussions, we knew instantly when we had found the ones we were after. Fully CNC machined with roll-formed threads these cores give themselves away with their spun-formed tops that keep the valve nut from unthreading too far. Most companies crimp the threads here which damages them such that the nut cannot thread over..we find the extra effort to spin form a perfect little mushroom head on the top of the valve to really say it all: these are carefully made. Icing on the cake is the use of fully synthetic seals for both the stem seal and the core seal, this means that the core will resist aging and cracking for far longer while being significantly more resistant to both synthetic and natural based sealants if you are using tubeless. Best of all, this additional thought, care and attention to detail costs almost nothing over lesser cores while saving you pain and suffering over the coming years.

High quality Presta Valve Cores!
These replacements valves are the quality you come to expect from Silca. They're neatly packaged with a handy valve core tool. If you're running tubeless keep a couple in your tool kit and saddle bag.

Silca valve cores
I was needing to buy some replacement valve cores for my mtb tubeless tyres. The old valves kept getting clogged with sealant, leaking, and not tightening up or being able to get them undone.
Theres lots of different brand valve cores that all look the same or very similar. These ones had the best description.
Ordered to the UK with no problems and took 16 days to arrive. I was kept updated via my parcel tracking app. I've not used them yet but I'll replace my valve cores with these new ones soon.
