The Company was an early pioneer in the development of hydrant type aircraft refueling equipment and related aircraft ground support equipment. Experience in this field led to the designing and manufacturing of pits required for the early hydrant systems. The company had traded under the name Garsite TSR. The Deer Park facility remained in New York as Garsite International until in December 1995, when GNY Equipment, Inc. (GNY) was spun-off to an independent status, bringing with it, almost a half-century of experience in aviation fueling, in liquid, Air, Oil and Gas equipment. The people at GNY have been manufacturing fueling equipment for over three decades.

GNY Equipment, offers Swivel Joint/Swing Joint for Mining Industry (Installed at Smelters - For Hot Air), Mooring (Submerged Services), Aviation, Oil and Gas Industry.

    ANSI 150 Class, 300 class or Speciality Flange. Designed as per API Spec. Standard 6H..
  • Material of Construction:
         Carbon Steel: ASTM Plate A515/A516 Gr. 60/70 (sizes upto 6" in CS A105 Forging)
         Stainless Steel: ASTM Plate/Casting of SS304/SS316 (CF8/ CF8M or equivalent)
  • Two different design constructions:
         Two Piece Design: The main seal replacement requires dismantling both bearings.
         Split Flange Design: The main seal can be replaced without dismantling any bearings.
  • Ball Bearing, fitted with two rows of widespread ball bearing (Chrome CS or SS).
  • Heavy-duty load bearing capacity widespread ball-bearing raceway hardened up to 345 BHN
    (equals to 37 Rockwell "C") through a special permanent metal hard facing process.
  • Seal Contact Faces are overlaid with Corrosion Resistant Stainless Steel (SS) Lining:
    All CS Swivel Joints are supplied with Special Stainless Steel lining at the main seal faces,
    on both nipple and housing for longer seal life and smooth rotation.
  • Triple Seal Design:
    Main seal of two different types: O-Ring or Lip Seal.
         O-Ring type: Main Seal of O-ring cross section of Buna-n/Viton® material and O-rings
         Lip Seal type: Main Lip Seal of PTFE (Teflon®) with Buna-n/Viton® Insert and O-rings or
                                 Main Lip Seal of Buna-n/Viton® is also available.
         A special Inverted Lip Seal design for main-seal is also available.
  • External Lip Seal For Submerged Application:
          A third additional seal specially designed to provide dust-free services.
          External Lip Seal of PTFE (Teflon®) with Buna-n/Viton® Insert or Buna-n/Viton®.
          A special Inverted external lip seal design is also available.
  • Positive and Negative pressures: Nipple (female) portion is specially dimensioned for the main seal
    to remain in the proper functioning position under both positive and negative pressure.
  • Designed to withstand temperature variations from -20 to 180 Deg. Centigrade.
          A special low or high temperature application is also available.
  • Factory Lubricated and Sealed: Lubricated with Special wear resistant high temp. PTFE based lubricant.
          Dust Proof.
  • Hydro testing and Special Testing: All Swivel Joints are Internally Hydro-tested at shop before shipping.
    The Air test, Vacuum test, Bending moment/Radial load test, Pull load test, Torque test, External
    Pressure test, Electrical conductivity test and Life Cycle Tests (US Patented) have been conducted
    during the R&D
    (research and development) and these tests can be conducted upon request at extra cost.
