vortek piston seals
« on: November 22, 2010, 11:52:31 AM »
tom sent me a ps28c seal and some of his white lube stuff to try in my diana 48. i have just gotten that thing up and running well. it needed a new breech seal and mainspring, also. now that my after-market .20 cal m48 is performing great, i'd like to propose a toast to tom gore and vortek products. my particular 1994 t-01 m48 sidelever w/ a .20 cal lothar walther match-grade barrel (factory length of 17") is shooting 13.5 grain jsb's out at 870 fps. it shoots 11.4 grain H&N FTT's out at 935 fps and crow mags out at 885 fps. the numbers mostly stay w/in 10 fps of these average velocities. after checking around, it appears that these chrony numbers are a little high ...... i attribute that to the ps28c piston seal from vortek. i have shot almost 1000 pellets through my new favorite airgun, the .20 cal diana 48. this is a very inexpensive part that all diana shooters should try. ....i'm ordering 2-3 more now. - paul d self. http://raneair.webs.com .

main squeezes: .22 custom disco (845fps w/ 13.5gr jsb)  .. .22 rws (older cometa) model 94 tuned (780fps w/ 15.5gr napier)..   .. .177 rws (older cometa) model 93 tuned for 12ftlbs (800fps w/ rws points)..  .. .20 cal/5mm fully tuned webley valuemax (780fps w/ 11.4gr ftt)..   .. custom crosman 2400pcpx w/ .25 (24ftlbs), .22 (20ftlbs) and .177 barrels (my daughter's when i can coax her into it)..  .. my only pistol - crosman ssp250 w/ everything

run and gun

just scroll down to the one you need. I'd get the one with the seal for 10 bucks more. I've got a pg2 kit in my 350 and 470. The 470 has the seal also and shoots harder than my 350, my 350 is about to get their seal. They are great kits and will transform your gun. Very easy to install also. By far a great deal! They have outstanding service and return emails quickly. Quick shipping, usually gets to me in nc in about 2-3 days. Great company to deal with.  Good luck!
