Amazon item #B01JB6D0YG **Q: I have 3200 psi /2.6gpm would this work and does the tube for trasporting the liquid come included?** A: I would suggest General Pump Model #100774 (Amazon Item #B01JB6D0YG) which is for 2-3 GPM machines. The suction tube is not included. Amazon item #B00O45UHUU would work great. **Q: What size is the threading ?** A: Both sides are 3/8" NPT threads. ## Frequently Bought Together - General Pump 3-5 Gpm Chemical Injector 100775 - 2 Sets Hotop NPT 3/8 Inch Stainless Steel Male and Female Quick Connector Kit Pressure Washer Adapters (Internal Thread) - MTM Hydro Original DN10 Italian Brass Plated Ball Valve for Pressure Washing, Soft Washing and Industrial Applications --- ## 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.ar/products/142328425-general-pump-3-5-gpm-chemical-injector-100775](https://www.desertcart.com.ar/products/142328425-general-pump-3-5-gpm-chemical-injector-100775) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-20*
