Review: Great product, durable and flexible. - I like how dang stretchy these things are, though they still seem strong enough for any job you need it for. I’m only using the vacuum caps for now on my car under the hood because I took some emissions systems off and needed to cap some holes off. The largest green cap seemed WAY too small to fit over one of the holes, but I just put some soapy water on the piece and it slipped right on! It still had some room to stretch too so it doesn’t seem like it will fatigue or get ruined by heat any time soon. I also like how long the caps/plugs are cuz it really makes it easy to customize to whatever length you need. The only thing that isn’t ideal is the colors of these. It would be nice if they offered the same set except in black so it would look more professional under the hood, but I knew that going into this. No complaints!

Overall works as intended and save me a ton of time. ## Frequently Bought Together - 350pc Ultra Precision High Temp Silicone Rubber Plug & Cap Kit Powder Coating Custom Paint Supplies - High Temp Masking Supply 235 Piece Silicone Rubber Plug Set - Sizes 1/32" to 1" - Tapered Stoppers for Powder Coating, Painting, Ceramic Coating, Sealing Holes - Non-Toxic, Flexible, Reusable - 20pc Extra Large High Temp Silicone Rubber Plug Kit Powder Coating Custom Paint Supplies --- ## 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.com.sa/products/15830628-350pc-ultra-precision-high-temp-silicone-rubber-plug-and-cap](https://www.desertcart.com.sa/products/15830628-350pc-ultra-precision-high-temp-silicone-rubber-plug-and-cap) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-08-20*
