One of the more common applications of HYMAX GRIP Cut-in Sleeve is making restrained connections to fire hydrants without thrust blocks. When a connecting pipe needs to be replaced, the HYMAX Cut-in Sleeve is the perfect solution for getting the job done quickly and securely.
The product can be easily coupled to the pipe in the ground using the HYMAX GRIP connection. With the T-handle and its open bore design, the HYMAX GRIP Cut-in Sleeve is easy to line up and slide onto the connecting pipe. Once in place, there is only one bolt to tighten compared to as many as 10 bolts on similar products. The fire hydrant can then be lowered to be connected with the mechanical joint end of the product.
HYMAX GRIP MJ Cut-in Sleeve is made of ductile iron and it’s the first transition coupling that can connect to a mechanical joint while restraining the connecting plain pipe with only one bolt to tighten. In some cases, it can also replace two products that connect between pipes. All of this means that repairs can be made faster while restraining the pipe without thrust blocks or rodding. Faster repairs mean less time in the ditch which helps make repairs safer too.
The HYMAX GRIP connection features gripping teeth that provides a strong circular restraint around metal or plastic pipes. As the pipe applies axial pressure, the GRIP chain increasingly tightens over the pipe, preventing pullout. The HYMAX GRIP technology allows the connecting plain-end pipe to be adjusted as needed – that helps save time on cutting and installing extra pipe. The HYMAX GRIP Cut-in Sleeve has a wide working range for connecting pipes of different diameters, meaning that you don’t need dedicated-sized transition couplings to help reduce inventory costs and save on shelf-space.
As with all HYMAX GRIP products, the HYMAX GRIP Cut-in Sleeve allows dynamic deflection of the pipe for up to four degrees per side, reducing future pipe cracks and breaks. When you install the HYMAX GRIP Cut-in Sleeve, you are effectively transforming the pipe connection into a flexible connection. It’s like a shock absorber in your pipe to handle shifting ground and this is something that can help save on repeated repair costs.
