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! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Bound to fit *by D***3 on 11 February 2026* Excellent selection of sizes, handy box-let's hope the catch doesn't fail!
