NEW* Vortek PG4 STEEL HW97 Tune-kit   

NEW* PG4 "STEEL" HW97 tune kit with high-yield spring helical guide top-hat
                                             Manufactured STEEL Body PRO-GUIDE4 STEEL tune kit provides another level to damping.
With its  new mass, weighted rear retainment guide, stiffer beam strengh the new PG4-Guides STEEL quickly counters  movement deading spring firing noise. The Inner guide arrangments are machined slip-fitted into spring plus+ an helical gripping guide to the spring internal guide. As well  also the 4th guide "top-Hat" has the exact spring fitting pitch allowing spring a thread like firm tighter fit apond firing. The spring with open coils  allows use of all coils for more accurate output across product line. Further, the DiY tuner has option of cuting spring for finer tuning. The new PG4-Guides have a near fit to its power grid with a heavier guide adding weight, beam-strength for spring equaling less fatigue, better sound deadening.

Performance with VacSEAL26:
High-Ouput full power up to 18ft/lbs/26 Joules
*1100fps(.17cal)/290 m/s CP7.9g
*710fps(.22cal)/220m/s G14.33CP (Lead pellet) (16ft/lbs)
*930fps(.22cal)/287 m/s G9.56g (tin pellet) (18.5ft/lbs)


Product Code:
PG4S785124230Hth

Contents of PG3 Steel Tune Kit: 
  • PG4 STEEL + 2 DELRIN  INNER GUIDES   
  • High Yield valve wire power spring
  • Lubrication for metal, plastic and seals 
 Installation:
  • For Consideration when tuning power:
    It is the owners responsibility to assure legality of their air gun power output.
    Vortek’s Location of testing is 578 Feet.Above.Sea.Level. (F.A.S.L)
    For every 1000ft above or below will be approximately .029 difference in velocity, thus foot pound (Ft/lb, Joules) of shooting energy.

    1000 F.A.S.L.x .029 = 29fps approx
    Joules= .7475=ft/lb

    Easy, do-it-yourself with vIrtually no pre-load force on assembly. 
    Works will all HW trigger arrangements 
  • **OPTIONAL PISTON SEAL: 
    **Special Note for   OLDER HW/77 air rifles having smaller compression chambers~

    Your HW77 airgun serial# before 1446049 has an 25mm Compression Tube Bore!! Choose 25mm VacSEAL
    We Highly recommend the install of our VacSEAL25 or 26 with the new PG4 STEEL. 

    Though the PG4 STEEL Tune-Kit does not required a change of the OEM piston seal to work... Although testing bewteen OEM and Vortek26 moly seal, we found greater performance when our VacSEAL25 or VacSEAL26 design was inside. Due to the enhanced radial stiffness of the weighted steel PG4, and the damping properties of our VacSEAL design. Upon closer of firing sequence the VacSEAL26 piston geometry did increased performance output dead-blowing sound and movment at the closure of the shot cycle.
