A combined inlet and outlet fitting for a fluid handling mechanism comprising a block having an inlet passage and an outlet passage having corresponding one ends adapted to be connected to the mechanism and the opposite ends thereof extending to the same one longitudinal end of the block. A coupling is attached to said one end of the block so that it can be moved arcuately relative to the block. The coupling has inlet and outlet ports connected to said inlet and outlet passages, respectively. Fastening means are provided for releasably securing said coupling in fluid-tight sealed relationship with said block.

Combined inlet and outlet fitting

An inverted bucket-type steam trap has a completely sealed casing of uniform wall thickness and preferably made of stainless steel. The casing is comprised of an upper part and a lower part. The lower part and the upper part both have a cylindrical wall portion which is open at one end and closed at the other end by a spherical segment-shaped bottom wall. The upper part and the lower part are affixed to each other by welding. The upper part has sidewardly extending outlet and inlet fitting means welded thereto. A valve is provided in association with the outlet fitting means. An inverted bucket is movable vertically inside the casing in response to the presence of condensate therein to operate the valve between opened and closed positions. An inlet tube is provided inside the casing and it extends from the inlet fitting means into the lower end of the bucket.
