Evaluation of compression-type tube fittings for use at INEL

INEL has been using mostly Swagelok compression-type tube fittings for more than 20 years. Suppliers of other similar lines of tube fittings have complained that fittings for warehouse stores should be purchased on a competitive bid basis. Previous studies on this subject have recommended the continued use of Swagelok on a sole-source basis. This policy has been maintained, but not formally stated to suppliers. Continuous marketing pressure from Gyrolok and Parker-Hannifin has resulted in a decision by the EG and G Idaho, Inc., Materiel Division and DOE-ID personnel to formulate a uniform policy on the warehousing of compression-type tube fittings. This report was prepared to give the EG and G Idaho, Inc., Materiel Division and DOE-ID management the best available information necessary to make a rational decision. It is concluded that the Swagelok fitting is the best available product of the three evaluated from the standpoints of technical adequacy and overall cost to the Government. It is recommended that INEL warehouse only the Swagelok brand
