If you have your pump for long enough...
It works fine especially for smooth sided valve stems. Much longer lasting than the original black ones.

Easy repair of your Silca pump
I was ready to pitch the old Silca bike pump. When I saw that it could be repaired with a rubber insert I ordered one immediately. Simple installation, pump works like new.

Guarnizione perfetta per i vecchi cappellotti Silca
Ricambio ottimo: calza perfettamente la campana delle vecchie pompe Silca (la mia ha più di vent'anni) e ne ripristina la funzionalità.C'è anche scritto che <dovrebbe> durare almeno 5 volte la vecchia versione nera, vedremo: per adesso sono MOOOOLTO soddisfatto!

ポンプが新品のごとく復活
3日に一回程度の使用頻度で、前回の購入からカウントして4年と一ヶ月使用可能だった。ゴム製であることを考慮すれば耐久性は満足てきるレベルだと考える。交換直前の数回は空気が抜けるのが分かるため、変え時であることが分かる。
