Any of the Trojan® watering nipples can then be easily installed using pipe thread tape or pipe dope. Sealing ring resists buckling
or slipping during installation. Sealing ring is designed to provide a complete 360 deg seal, even when it is not perpendicular
with barrel. Locknut enables easy application of torque with wrench. Sharper and deeper teeth to improve bonding. Precision
machined tapered threads designed to create watertight union.
