WD-40® Specialist® Penetrant with Flexible Straw has a fast-acting formula with attached 8-inch flexible straw that bends and keeps its shape, giving you unlimited access to hard-to-reach jobs.

  • 8” Flexible Straw
  • Ideal for use on nuts, bolts, threads and locks
  • 50-state VOC compliant

Mr Safeway

Love the flexibility

As a pro board member I allow friends and coworkers to use the WD40 products I receive and this one topped the list. I as well as all that used it not only loved the results it delivered but the flexibility it allowed to get to some right places, everyone could not tell me one flaw! Great job WD40.

Awesome product, love the flexible straw

I love this product with a flexible straw. I run a small shop and we have to squeeze every dollar and with this flexible straw you can get the product right on the area needed with out much waste and it doesn't hurt that it's spraying out the good ole WD-40.


Works great

Have used this on a large remodel project where we have had to dismantle a larger number of metal racks and frames. This works quickly and the flexible nozzle makes reaching concealed bolts extremely easy.


A Great Product.

A great design , You use less product because you can be very precise with the flexible straw.


Great product

The new wd40 specialists penetrant is a great product to be used on anything and everything in your garage. It has worked great when removing seized bolts all around the car especially lug nuts that were rusted on. The new flexible hose/straw they use on this products can should be added to every wd40 product out there that comes in a can. It works that good. All around awesome stuff. I will always have a can on hand!


Specialist Formula works great!

I got this and used it to free up some locked up nuts on my motorcycle. Took just a few seconds to work it's way in and they broke nice and easy after messing with it for a few hours.


Great product for hard to reach places

I love this flexible nozzle it has enabled me to reach those impossible places with ease


Excellent improvement

With the flexible attachment I was able to lubricate the inside of my truck tailgate which makes it open and close smoothly now. Makes the old fashion plastic straw obsolete.


Better than sliced bread!

The addition of the flexible straw means that I get the product where I want it, the first time, every time!


Useful Improvement

The WD40 product is like the Kleenex of tissue and does so much more than lubrication and loostening of rusted bolts and nuts. The Flexible straw is an improvement that helps pinpoint the targeted area greatly reducing the amount of over spray.
