SIGMA now the only manufacturer to offer 3’-60” Restraints for PVC Pipes in the US
SIGMA Corporation is proud to introduce the One-Lok Model SLCE wedge action restraint for 42” & 48” PVC pressure piping. The new One-Lok has a unique design, which allows the product to act as both a pipe restraint and as a gasket compression gland. Additionally, the restraining glands have been designed to minimize the assembly time required to install the joint. This feature differs from competitors’ products, which require the use of an additional mechanical joint follower gland. As a further benefit to customers, the same restraining gland can be used for both mechanical fitting joints and bell harness PVC joint assemblies.
Features of the One-Lok Model SLCE wedge action restraint for 42” & 48” PVC pipes include:
- Fewer wedges and break off bolts are required during installation (when compared to the number of T-Bolt holes). This feature greatly reduces the installation time required for proper joint assembly
- Additional extended lugs for the gasket bell OD, which can be used for bell harness PVC pipe joints
- Same wedge & break off bolt for 42” & 48” sizes, which will provide interchangeability between what??? (different sized pipes??)
- Internally tested, approved and recommended on all classifications of 42” and 48” AWWA C900, including thin wall pipes
- Restrainer glands are supplied with Sigma CORR-SAFE e-coated for enhanced corrosion protection
- Supplied as a pack, which includes the standard T-bolts and nuts, as well as SIGMA’s enhanced sealing capability with the SIGMASeal mechanical joint gasket
- Product is available upon request with Stainless Steel or Fluorokote/Teflon T-bolts and nuts
SIGMA remains the industry leader for North America in pipe joint restraint and with the launch of these restraint sizes, is now the only manufacturer to offer a nominal size range of 3” through 60” gland replacement wedge action restraints for PVC pressure pipes. Steve McDonald, SIGMA’s Restraint Joint Product Manager commented, “We pride ourselves on designing, developing, manufacturing and supplying products that meet or exceed end-user expectations. Our loyal customer base shared with us that there was a need for this wedge action restraint and our Restraint Engineering team led by Satheesh Chandrasekaran made it happen!”
