  ATEX-Sight glasses, Aluminium / ESG glass

  GANTER

  ATEX-Sight glasses GN 743.6 are suitable for use in an explosion risk environment. They comply with the guidelines 94/9/EG.Detailed documentation is available and forms part of an order for this product.
  A detailed operating instruction is included with every GN 743.6 sight glass. In addition, the housing is provided with an ATEX-label.
  Further salient points of the oil level sight glasses GN 743.6 are:
  Genuine glass of high stability and scratch proof. The sealing is achieved with an O-ring on the periphery and not on the face edge of the glass. Leak tightness is therefore not affected by axial pressures.
  The sealing ring is embedded in a radial groove and cannot drop out, nor can it be extruded when tightening torque is applied.
  
  Sight glasses GN 743.6 can be used on pressurised oil tanks. Tests regarding maximum pressure are available on request.
  Assembly instruction:
  For mounting on walls of less than 4 mm thickness please use a fixing nut GN 543.1.

  Oil level sight glasses with conical thread

  GANTER

  The conical thread of the oil level sight glasses GN 743.7 makes a metallic seal possible. When tightening the conical male thread R it blocks itself with the appropriate cylindrical female thread Rp.
  With the datum plane a the R-male thread has the same thread diameter as the Rp-female thread, so that it can be screwed in by hand. The strong tightening by means of a tool increases the length of engagement and seals the screw connection. Additionally a sealant (hemp or fluoropolymer band) is usually used. The R-thread is „roughened“, so that the sealant does not shift when screwing in.

  Oil level sight glasses, Aluminium / Float glas, resistant up to 100 °C, blank

  GANTER

  Oil level sight glasses GN 743 offer genuine glass of high stability and scratch proof. The sealing is achieved with an O-ring on the periphery and not on the face edge of the glass. Leak tightness is therefore not affected by axial pressures.
  The outside diameter of these oil level sight glasses with recessed hexagon is chosen to match mounting holes for tube connections according to DIN 3852.
  The seal is housed in a groove and it can therefore not be lost. In addition, this groove prevents the seal from being extruded when the sight glass is tightened.
  Oil level sight glasses GN 743 can be used on pressurised oil tanks. Tests regarding maximum pressure are available on request.
  Assembly instruction:
  For mounting on walls of less than 4 mm thickness please use a fixing nut GN 543.1.

  Oil level sight glasses, Aluminium / Plastic

  GANTER

  Oil level sight glasses GN 744 in type A use the so called prismatic effect of a cat’s eye to display the oil level unaffected by oil colour or oil viscosity. The advantage of this effect is particularly obvious in the case of under or overfilling or for inspection under unfavourable light conditions.
  The seal is housed in a radial groove in the aluminium body and hence cannot be lost. In addition it cannot be extruded when thigtening the sight glass.
  Oil level sight glasses GN 744 can also be used on pressurised tanks. Data of pressure an vacuum pressure tests is available.
  Assembly instruction:
  For mounting on walls of less than 4 mm thickness please use a fixing nut GN 543.1.

  Oil level sight glasses, Aluminum / Perspex

  GANTER

  This oil level glass GN 537 does not require a thread.
  The oil level sight glass is inserted into the bore d2 to H11. By simply tightening the ring nut using the pin key the seal is pressed against the contact surface which, at the same time, will hold the sight glass in position. For removal reverse the procedure.
  Their application is limited to non-pressurised or only slightly pressurised tanks.
