✦ Synopsis

copper flanges, no leakage was detected with the range of the sensitivity of the detector, 2.3 x 10 -~~ arm cm~s -~ div -~. In tltis test, it was found tlmt both silver.plated and Teflon-coated O-rings, which had once been used and dismounted, could satisfactorily be used in superfluid helium at least once more. Seals with O-rings neither silver-plated nor Teflon-coated were not leak-tight even at room temperature; accordingly, the plating with giver or coating with Teflon is essential for ensuring leak. tight seals.
