Title: Wanted a small piece of PEEK
Post by: rualert on August 17, 2022, 12:34:12 PM

     Mods, if this is the wrong place to ask about this specific machining material, please move as required.
All, I'm looking to purchase a maybe 6-inch long piece of PEEK rod for some poppet work, and such. If anyone is willing to part off a short piece, even maybe a 4-inch piece. I'll happily purchase it with of course shipping.

Thanks,
Casey

Ebay is my goto for short rods of peek, even scored some Tecapeek PVX.

Hi Casey, yeah my suggestion would be to look at eBay, Amazon, or Grainger.  The prices an individual has to pay to ship a small inexpensive item these days makes it a false economy.  Can usually get it for the same price and more quickly from a vendor who ships large volume and gets dirt cheap shipping.  I mean, hopefully someone will step up but you may be waiting a while.
 
Otherwise I just wanted to mention I’ve looked at bearing-grade PEEK and its compressive strength and hardness are on the same level as “plain” PEEK, so don’t get analysis paralysis or go nuts trying to find a specific kind of PEEK.  Bearing grade mainly has to do with improved self-lubricity and thermal conductivity, neither of which carries any significance for a poppet.  But if you find some at a good price, it will work every bit as well.

Neither of the vendors I had saved have it in stock.  The best deal I saw on peek is this one.  There is another vendor selling .750" X 2' for $40 shipped.  3/8" should be large enough.

This is what I use, 5/16" cost about $10 delivered for a 12" stick.

Poppet no use for PVX, ...used PVX replacing a Vevor second stage piston seal where heat and friction are an issue.

Point being variety of materials available at low volumes, shipping is a bear.

     Thank you to everyone who has pointed me in a decent direction, and pointed out that the use of bearing grade to save a bit as I saw a 12" piece I believe it was 3/4" for 60 bucks, and thought that seemed a bit high for a polymer that has been around for quite a while. I'll see if our local Grain=ger has any in stock, and just go pick it up as noted to save the shipping. the only one I found on Amazon where I have Prime, was the $60.oo stuff and a couple of weeks out.

Thanks all,
Casey

     Thanks to everyone again. I did finally get some from an eBay vender in just a few days for a reasonable price for both a small diameter stick, just right to make popets with, and a 1/2 inch diameter rod as a bundle.
