If you're working on small engines, this PAOSDKSUI oil drain hose is a direct replacement for part number 1723165SM that fits a bunch of Briggs & Stratton engine models. The 3/8 NPT fitting is standard for these applications, and the 10.5 inch length gives you enough flexibility to position your drain pan comfortably. Made from high-strength steel and rubber construction that can handle the heat and pressure - rated for temperatures up to 300°F and pressure up to 700 PSI, which is more than enough for typical small engine oil draining. Compatible with B&S Model Series 29, 30, 35, and 38 engines, plus Series 40, 44, 49, and even the larger 54-61 series engines. The black finish is corrosion-resistant, and the build quality feels solid, not like those cheap aftermarket parts that fail quickly. Installation is straightforward if you're familiar with small engine maintenance - just remove the old hose (if present) and thread this one into the drain port with proper sealant. The rubber section is flexible enough to route where you need it but stiff enough that it won't kink and block oil flow. Much more affordable than buying genuine Briggs & Stratton parts but still reliable for the job. Perfect for lawn mowers, generators, pressure washers, or any equipment using these common engine series. The 3/8-18 fittings are precisely threaded for a secure fit without cross-threading issues. Definitely one of those replacement parts that's good to have on hand if you maintain your own equipment. The quality is consistent with OEM specifications, so you don't have to worry about fitment problems or premature failure. Saves you money compared to taking your equipment to a repair shop for simple maintenance tasks.
