摘要： PROBLEM TO BE SOLVED: To obtain a putty material of which the binder component does not migrate to a resin member and which extends the useful life of a resin pipe coated therewith by compounding an oily binder, a fibrous material, and an inorganic powder. SOLUTION: This putty material contains 5-30 pts.wt. oily binder, 0.001-0.5 pt.wt., fibrous material, and 50-100 pts.wt. inorganic powder. A silicone oil is an example of the oily binder, a dimethylsilicone oil being especially preferable. The binder is one having a viscosity of about 5,000-100,000 cP, preferably 10,000-30,000 cP. Organic fibers, inorganic fibers (e.g. carbon fibers), metal fibers, etc., are listed as the fibrous material, carbon fibers being especially preferable. Though the lengths and diameters of the fibrous material are not specifically limited, usually the lengths are about 1-7 mm and the diameters are about 10-30 μm. Clay, tale, calcium carbonate, and silca are each preferable as the inorganic powder.

摘要： PURPOSE: To provide a soft pipe connecting joint for preventing the propagation of the torsional pressure due to the turn of a box nut to a coupling pipe by a tightening ring for tightening-fixing the end part of the soft pipe, since a torsion is generated on the soft pipe by the turning operation of the box nut when the soft pipe is tighteningly fixed with the connecting joint in the conventional. CONSTITUTION: When the outer peripheral surface of a tightening ring 3 which makes contact with the inside diameter surface of a box nut 2 is applied with the slide surface work, the propagation of the torsional pressure due to the turn of the box nut to a soft coupling pipe P by the tightening ring for tightening-fixing the end part of the soft pipe is prevented. Accordingly, the inside diameter surface of the taper hole of the box nut 2 slides on the ring edge 31 which is slide-surface-worked and is screwed, and the tightening of the box nut free from torsion is carried out, preventing the propagation of the force in the turning direction to the soft pipe, and the reduction of the endurance years of the soft pipe due to the torsion and the deterioration of the softness due to the fatigue of the material can be effectively prevented.
