Bar-Type Puller has cross block with a central section. It has pair of end sections with a forcing screw threadably mounted in the central section. It can be radially and axially adjustably mounted on the cross block by end sections of the cross block. The pins are caused to move into binding relation with the cross block. There is also provision for axial adjustment by providing additional spaced pins.

Barbed Nipples are made up of both plastics and metals. Plastics like PVC, CPVC, and polyethylene are used for making barbed nipples & metals like iron and steel. Barbed nipples have edges or points arranged at intervals on the upper side of the nipples. These barbed nipples are used for connecting pipes and used inside a hose to seal one end. The use of barbed nipple helps to stop the leak of liquids in the pipes and hoses, since the nipples are barbed the sealing of the pipe or hose with this nipple will be very tight than in the usual nipples.
