Specs where right. Need to use for my remote control boat. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Perfect! *by A***R on Reviewed in the United States on April 16, 2020* Received earlier than expected. Exactly as described. Perfect! ### ⭐⭐⭐⭐ 4.0 out of 5 stars Hope you don't need the exact length. *by B***N on Reviewed in the United States on March 5, 2019* Looks like they cut these to length with an abrasive chop saw. The cuts are not straight and there is a lot of flashing and burrs. After trimming both ends it worked out fine. I threaded the ends for what I needed and it worked fine, there is enough wall thickness for 10-32 threads to be cut. --- ## 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.tn/products/78821230-2-x-304-stainless-steel-capillary-straight-tubing-od-4mm](https://www.desertcart.tn/products/78821230-2-x-304-stainless-steel-capillary-straight-tubing-od-4mm) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-05*
