This listing is for both the non anodized oil change/filler tube and magnetic dipstick.

The dipstick has M18 x 2.5 threads and is 1-7/8" long from the end of the dipstick to the shoulder above the O-ring.

The oil change tube extension has M18 x 2.5 threads. They are known to fit the following generator models:

WEN 56200i, WEN 56125i, WEN 56310i, WEN 56310i-RV, WEN 56202i, WEN 56380i, WEN 56225i, Yamaha, EF2000iS, Yamaha EF1000iS, iQ2000, Powerhorse 42411, & Predator 2000

Oil change/filler tube:

As the owner of a generator, you probably know the challenges of changing oil. Trying to change the oil without some type of aid is a mess, and filling can also be messy. This oil change and filler tube will allow quicker and easier oil changes than any other method on the market.

There are several versions of oil change tubes, why should you consider this version? Although the basic principle is the same as others, there are improvements that make this design better:

1. A hexagonal body vs. round body

Why is this version hexagonal instead of round? A round piece is difficult to grip, especially when any oil gets on it. A knurled surface is difficult to clean. A hex allows for easier gripping with fingers (or if needed, a wrench). The flat surfaces are also easy to clean. 

2. A flat O-ring vs. round O-ring

Why is a flat O-ring used? A flat O-ring is supplied for better sealing and longer life.

The tube is CNC machined from 6061 aluminum to high quality standards.  

 

Magnetic oil dipstick:

Why should I consider a magnetic dipstick over the stock dipstick? Like the magnet on the drain plug of several models of automobiles, a magnetic dipstick will pull any ferrous metallic fines from normal engine use that are in the oil. Since these small engines do not have an oil filter, this will help extend the life of the engine. This will help protect your investment while maintaining the functionality of OEM. The high temperature super magnet is partially recessed inside the dipstick and secured with an oil tolerant, high strength (4500 PSI), high temperature retaining compound.

There are other versions of magnetic dipsticks, why should you consider this version? Although the basic principle is the same as others, there are improvements that make this design better:

1. A hexagonal body vs. round body

Why is this version hexagonal instead of round? A round piece is difficult to grip, especially when any oil gets on it. A knurled surface is difficult to clean. A hex allows for easier gripping with fingers (or if needed, a wrench). The flat surfaces are also easy to clean. 

2. A flat O-ring vs. round O-ring
