    Exactly the needed part
    This was the correct part and fit and functioned perfectly. I wish there had been some instructions with it for installation. I finally warmed it enough to stretch it over the rim and into the groove.it then functioned perfectly.

    Blown seal in a 20 year old Senco finish nailer

    Thinking I would never find a seal for such an old product I was shocked that you folks actually had one. I ordered one and within just a few days it was here. Using allen wrenches I had no trouble removing the top panels and the broken plastic seal. The hard work.was trying to stretch the new seal over without breaking it. That's when I thought I should of ordered a couple of backups. There must be a special tool for this procedure. I could only get the seal about 2/3 on by hand no matter how hard I tried when I decided just do it, and used a pair of channel locks and pried it into place without damaging the seal, I hoped, put everything back together, fired up the compressor, loading the nail gun and it works to perfection. Celebrated with a cool one and toasted to you guys for making my day.

    Removed the four screws from the top cap of the stapler, took the top, then out pulled the plunger, replaced the seals put oil on them so they would go on easy then put it back together, plug air up and works like a charm it was simple. You should not have a problem just pay attention.

    I tried some of the ideas from other people like boiling in water to make it more pliable and using oil, I found starting by hand as far as I could then using a flat tip screwdriver to stretch and push down a little at a time I could walk it around.

    Installed all the new seals I ordered. The nylon seal needed to be heated up so it would streach. I put it in a dish of water and microwaved it for one minute on high, that made it just flexible enough to get it on to the piston top.
