We haven’t yet experienced a Dyme made hose assembly made to spec not fitting, but if this were to happen, Dyme has a 100% No-Risk, Perfect Fit, Money Back Guarantee. Where if a hose is not made to spec, we will make the necessary tweaks or we’ll refund 100% of your money. We would just request that you email us at launch@dymepsi.com so that we can send you a Return Merchandise Authorization (RMA) form to fill in.
