A tubular tool includes a tubular first part and a tubular second part. The tubular first part including a first section having an engaging hole defined in the distal end thereof, and a second section having a connection hole defined in the distal end thereof so as to be respectively connected to a driving tool and an object. The tubular second part is rotatably mounted to the first outer periphery of the first section of the first part. At least one lip extending from the inner periphery of the tubular second part. At least one first circular rib extends outward from the first outer periphery of the first section. The at least one lip is engaged with the at least one first circular rib to restrict the second part from separating from the first prat.

A sprinkler wrench for installing a sprinkler includes a base having a tool engaging portion. A sidewall extends from the base and a sprinkler engaging portion extends from the sidewall. The sprinkler engaging portion includes a pair of oppositely facing surfaces defining an outer perimeter and a recess including two opposing flats. A protective boot cover is removably attached to the sprinkler engaging portion and includes flat cover portions covering the two opposing flats.

A tool for engaging with a backflow valve handle includes a body forming a channel extending from a first side to a second side, the channel extending upward from a bottom surface of the body; and an adapter extending from a top surface of the body, the adapter to receive a hand tool; the channel is to secure over the backflow valve handle; and the adapter is to receive torque from a user to loosen the backflow valve handle.

Infiltrated diamond bodies for use in gripping drill rods and other tubulars. One example of such an infiltrated diamond body is a cast diamond roller having a plurality of pads that are separated by channels. Another example of such an infiltrated diamond body is a cast wrench jaw having at least one raised jaw pad.

The existing gripping tool are made of or covered with non scratchable material to prevent damage to articles on which they are being used. The scratchless tool may be modified either partially or fully to accommodate a softer surface made of non scratchable material. They can either be co-moulded or attached or bonded or inserted to the existing metal tool during manufacturing or use.
