This is angle valve also popularly called tee tap. Made of stainless steel with flange. Size: 1/2x1/2''. Norminal pressure max 10mpa. This angle is a true mark of quality. Its far better than cheap low quality tee tap circulating in the market today, which often start leaking water few months after installation. In some cases the control stop working thereby filling everywhere with water but this tee tap is not like that. It is very reliable and strong, the control is one turn no problem at all. Buy genuine product, buy good quality and have rest of mind. Thank You!
