Too soft for my application, raw water intake in boat. Vacuum of pump will collapse this faster than fox stealing a chicken. This is more flexible than a garden hose. ## Frequently Bought Together - FlexFab - 1-1/4" ID x 1 ft (Sold Per Foot) 5526 Blue Silicone Heater Hose 32mm 350F Radiator Coolant 1.25" - ICT Billet 1-1/4" to 1-1/4" Inch Hose Barb Splice Coupler Repair Fitting Adapter Connector Radiator Coolant Intercooler Heat Exchanger Fluid Designed & Manufactured in USA Bare Aluminum AN627-20A - AC PERFORMANCE ID 1.25" (32mm), 90 Degree Elbow Coupler, Leg Length 3.5" (90mm), 3-Ply Reinforced, Automotive Pure Silicone Hose, Black --- ## 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.vu/products/200808283-flexfab-1-1-4-id-x-1-ft-sold-per](https://www.desertcart.vu/products/200808283-flexfab-1-1-4-id-x-1-ft-sold-per) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-02*
