Jtherefrom and provided with lateral extensions or feet 22. The spring arms extend inwardly as The shown in Fig. 2, and the extensions 22 engage the lips I6 and I l 'with yielding pressure and urge them against each other to form avsealing contact. As shown in Fig. 3, the tube 9 is slightly y elongated in its lower region so as to accommo-I date the increased length of the seal member I2 when it is collapsed as shown. In this connection,

` it maybe stated that'the originalforin of the #sealing `rz'iflenrilo'er may be such that the lips F6v and El areiri substantial contact with each other as anormal condition. However, this is nota necessary prerequisite since the spring arms `2`I will serve to collapse the member and bring th lips into engagement.

A protecting element in the `form of ay'iehzlv` as a seal is also provided by the parts engaged 'between the bushing 8 and the shoulder Il. Also, the tapered plug part 49 seals against the tapered seat 4 I When the keg is to be tapped the outside sealing disc is turned from the position shown in Fig. 2 to the position shown in Fig.`5,` and this also shifts the inner dise out of posi- I l tion. Then the fixture 50 is applied tothe bushing `8 and a seal connection is obtained at the `packing 5I The draft tube is now pushed down- Lxrllardly into -the barrel` and the packing nut 51 is tightened to form a seal at lthe packing 56. As

the draft tubeis pushed downwardly, its end first I ltengages the tapering fingers 21 and expands the isnarnejand therefore lexpands the tapered walls l5 of: the rubber sealing element. Thus the rubing sleeve isdisposed within the rubber sealing member. .This protectingmember has a tubular. 1
