In addition, the cross-sectional diameter of the ring & the Overall diameter would need to match one of those provided in the kit. If the existing washer is actually a 'washer' i.e., with a rectangular cross-section, then you would be taking a chance. **Q: Will any of these fit on the bosch pressure hose?** A: As I do not know the dimensions of the Bosch pressure hose, it is not possible to answer this specific question. However, the pack of O-ring gaskets has a good range if sizes (as indicated in the illustration) and I think it is highly likely that there will be a gasket to fit the hose. **Q: It is size for inner or outer please?** A: They are all different sizes. I just kept swapping them about until I found one that fitted well! ## Frequently Bought Together - 250 Pcs O-Ring Gasket Kit, 15 Sizes Rubber Washers Seals Assortment Set, Assorted Electrical Gasket Rings, Insulating Plumbing Plumber Sealing O Rings Washers Set for Quick Repair - VCE 2 Pack PTFE Industrial Sealant Tape White Thread Seal Tape,12mm x 13m --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/343476991-250-pcs-o-ring-assortment-kit-nbr-rubber-washers-seals](https://www.desertcart.pl/products/343476991-250-pcs-o-ring-assortment-kit-nbr-rubber-washers-seals) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-15*
