| Features |
| Grooves |
Grooves are machine broached for excellent control of width, chamfer, depth, straightness, and spiral. |
Sealing |
O-ring seals prevent entry of grout. |
Coupling |
Built-in couplings snap together to make a flush joint. Unique locking mechanism engages full inner circumference of casing, providing much stronger joints than other snap-type casings. |
Assembly |
Press casing sections together until joint snaps closed. The resulting joint is strong, flush, and grout-proof. Solvent cement, rivets, or tape are not required. O-ring lubricant is applied at factory. Extra O-rings and lubricant are supplied with each box of casing. |
