Compatible with acetylene, propane, and Mapp gas, this essential safety device ensures your welding setup stays secure and reliable under pressures up to 290 PSI for oxygen and 21 PSI for acetylene. ## Description Never connect a torch to acetylene and oxygen tanks without installing a set of flashback arrestors in the hoses at the regulators. Without these safety devices, it is possible a flash can occur within the hose, and ultimately follow back into the tanks, causing an explosion. This would be an extremely rare occurrence, but flashback arrestors will make it a "never" occurrence. Check valves are only a first line of defense and may not ultimately stop a flashback. Only the flashback arrestors will. ## Features - Application: For installation between the regulator and hoses - Specification: Standard “B” Fittings (9/16"- 18 UNF) fits most twin hoses - Note: The acetylene arrestor in this set can also be used for Propane or Mapp gas - Check Valve: The one-way valve design allows the flashback arrestor to guarantee that gas can merely flow in one direction instead of back flow to prevent accidents - Brass Material: The flashback arrestor is formed by pure copper, which is sturdy and durability. The maximum bearing pressure of oxygen check valve is 20bar/290PSI. The maximum bearing pressure of acetylene check valve is 1.5bar/21PSI ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | RX WELDER | | Part number | RX WELD Flashback Arrestors | | Item Weight | 251 g | | Package Dimensions | 10 x 5.5 x 3 cm; 251 g | | Item model number | RX WELD Flashback Arrestors | | Size | clitoral vibrator 16 | | Color | Clitoral Vibrator 13 | | Style | for Regulator | | Material | clitoral vibrator 13 | | Shape | clitoral vibrator 13 | | Power source type | gas_powered | | Item Package Quantity | 1 | | Special Features | clitoral vibrator 13 | | Specific uses | clitoral vibrator 13 | | Included components | Flashback Arrestors | | Batteries Included? | No | | Batteries Required? | No | ## Images ![RX Weld Oxygen Acetylene Flashback Arrestors Set Regulator End - Standard "B" 9/16-18UNF Threads Size - Image 1](https://m.media-amazon.com/images/I/71f5u5ESjxL.jpg) ## Available Options This product comes in different **Style** options. ## Frequently Bought Together - RX WELD Oxygen Acetylene Flashback Arrestors Set Regulator End - Standard "B" 9/16-18UNF Threads Size - RX WELD Oxygen Acetylene Hose 1/4-Inch × 50 Feet with 9/16"-18 B Fittings, Torch Hose, Grade R - RX WELD Oxygen and Acetylene Regulators CGA540 and CGA510- Compatible with V-Style Welding Gas Torch Cutting, T-Handle --- ## 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.id/products/526741849-rx-weld-oxygen-acetylene-flashback-arrestors-set-regulator-end-standard](https://www.desertcart.id/products/526741849-rx-weld-oxygen-acetylene-flashback-arrestors-set-regulator-end-standard) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-13*
