    O-ring HW 100, 37.1 x 1.6 Cylinder clamp 2682C
    O-ring HW 100, 15.6 x 2.5 Barrel clamp 2682B
    O-ring HW 100, 32 x 2 Magazine 2603A*
    O-ring HW 100, 13 x 2 Adaptor A 2704
    O-ring HW 100, 2.57 x 1.78 Adaptor B 2703B

    O-ring HW 100, 3 x 1.5 Valve stem 2655D
    O-ring HW 100, 12 x 1.2 Breech block main (12 x 1) recommended 2658
    O-ring HW 100, 5.5 x 1 Breech/probe seal .22 2659A*
    O-ring HW 100, 4.5 x 1 Breech/probe seal .177 2659A*
    O-ring HW 100, 4 x 1.5 Probe buffer 2618A*
    O-ring HW 100, 2.57 x 1.78 Main valve inlet 2665D
    O-ring HW 100, 7 x 1.5 Main valve outlet 2666
    O-ring HW 100, 2 x 2 Main valve internal (2.57 x 1.78) recommended N/A
    O-ring HW 100, 7 x 1.5 Regulator piston 2668
    O-ring HW 100, 10 x 1.5 Tension adjuster (sometimes omitted) 2672
    O-ring HW 100, 8 x 1.5 Barrel 2679

    These were not available in my country. Hence I ordered an O ring kit from Airgun spares John Knibbs. Link is below;

    http://www.airgunspares.com/store/produ … 00SEALKIT/

    Surprisingly this kit does not have 7×1.5mm regulator piston and main valve outlet O ring.

    Please share the correct sizes of All the O rings being used in HW100 .22 41J 

    If I get correct sizes, I shall try to find them locally once again.

    Hi

    The Barrel clamp 2682B….Does not fit on FSB ,FUC version Weihrauch HW100T …!!!!

    Because of the shrouted barrel.

    The o-ring size that is correct for this model is : 20 x 1.5 ( 2682 )

    Regards

    Also the regulator piston's 2668 original size..7 x 1.5  would not cures leaks ,,,!!!!

    So the o-ring 2668 must be a litlle larger ( slightly )…The ideal size is : 7 x 1.7

    But this o-ring is rear to find …..!!!! So the second best is 6.8 x 1.8.

    both 7×1.7 and 6.8×1.8 = 10.40mm OD

     

    God Bless you all
