Review: Not horrible to deal with but not exactly easy either. - Tubing is very stiff. You will eventually get it to go where it needs to, but it won't be all that easy or fast. ('Sure beats working with solid black pipe though!) I used a standard PVC pipe cutter to cut the hose and it worked fine, but you need to be very careful to make straight cuts and the ends of the hose will require a little preparation before assembly. IMPORTANT! The inside of the hose absolutely MUST be chamfered or it will force the o-rings out of their grooves when the hose is pushed onto the fitting. I found a step drill that would accomplish this sort of ok if I tilted it and reamed it by hand (Not in a drill). It did ultimately work, but it was a bit of a time consuming hack. If I could go back in time and do it all over, I would definitely spend the extra $10 and get the correct MAXLINE BEVELING TOOL.

They mixed up my order. I ordered three straight fittings and two unions. I received two straight fittings and three unions. I’m sure Amazon will make it right. ## Frequently Bought Together - Maxline M8003 Straight Fitting for 3/4-Inch Tubing with 3/4-Inch Male NPT Thread - Maxline M7500 Master Kit, 3/4-Inch x 100-Feet - Maxline M8005 Straight Fitting for 3/4-Inch Tubing with 1/2-Inch Male NPT Thread --- ## 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.kw/products/7971519-maxline-m8003-straight-fitting-for-3-4-inch-tubing-3](https://www.desertcart.com.kw/products/7971519-maxline-m8003-straight-fitting-for-3-4-inch-tubing-3) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-16*
