JXHONG Engine Drain Port Oil Change Hose 3/8" NPT — 18" High-Temp 300°F Rubber with Steel Fitting

This compact oil drain hose is engineered specifically for engines with a 3/8" NPT oil drain port. It combines a durable steel/flared fitting connection with a high-temperature rubber hose so you can route used oil away from the vehicle and workspace without spills. Before ordering, confirm your engine uses a 3/8" NPT drain port—note that the "3/8" refers to the NPT thread designation, not the tube's inner or outer diameter.

How will this hose make an oil change cleaner and faster?

The JXHONG hose gives a controlled path for oil to flow directly from the drain port into a catch container, minimizing drips and splashback. Its flared outlet seals to flare fittings, avoiding the need for an O-ring and simplifying installation. The 18-inch length provides enough reach to position a drain pan or bottle without crawling under the vehicle.

• Direct 3/8" NPT male inlet mates with corresponding female ports.
• Flare-style outlet seals reliably to common receiving fittings.
• 18" hose length keeps oil away from chassis and hands.
• Fast hookup and removal for quicker service intervals.

Is this hose compatible with my engine's drain port?

This tool is designed exclusively for drain ports using 3/8" NPT threads. The NPT size is a thread standard and does not equal the hose bore diameter, so visual measurements alone can mislead. Check your engine manual or existing drain plug markings to verify a 3/8" NPT specification before purchase.

• Fits engines specifying 3/8" NPT female drain ports only.
• Replaces common OEM part numbers such as STAN1438, 1723165SM, 116-4924 in compatible models.
• Not recommended for other thread types (metric, BSP, straight pipe).

What materials and temperature ratings does it offer?

The assembly pairs a high-strength steel fitting with a heat-resistant rubber hose rated around 300–320°F and tested for pressures up to roughly 700 PSI in its design. Those specifications ensure the hose withstands hot used oil and routine shop conditions without swelling or failure. The durable construction helps prevent leaks and maintains a secure connection through multiple service cycles.

• Steel male 3/8" NPT inlet for secure threading.
• Rubber hose rated to approximately 300–320°F.
• Designed for high-strength, repeated use in workshop environments.
• Flare outlet forms a tight seal without an O-ring.

How do I install and store the JXHONG drain hose?

Screwing the male 3/8" NPT fitting into the engine's matching female port is the only required connection; the flare outlet mates with standard catch fittings. After use, drain remaining oil from the hose, wipe it clean, and store it coiled in a dry place to preserve the rubber and fittings. Routine inspection for wear or cracking will extend safe, reliable service life.

• Hand-thread the male NPT fitting into the female drain port until snug.
• Route hose to a drain container and connect flare outlet as needed.
• Empty and clean hose after each oil change; store coiled and dry.
• Inspect fittings and hose for damage before reuse.

Who is this for? The JXHONG 3/8" NPT engine drain hose is aimed at professional mechanics, fleet technicians, and DIY vehicle owners who service engines that specifically use a 3/8" NPT drain port and want a safer, neater way to remove used oil. It's not a universal adapter—buyers should confirm port thread type before purchasing to ensure a correct fit and reliable performance.
