The LS_LL style gasket is engineered to seal effectively at lower seating stresses. With this design, the gasket requires less bolt load to seat while still delivering the same recovery capability as a standard spiral wound gasket.

It is commonly applied on Class 150 and 300 flanges where users may be concerned about limited bolt preload. The gasket density can also be customized to meet a wide range of service conditions.
Our production system ensures precise, high-quality welding with consistent spacing, the correct number of metal plies on the inner diameter, an optimal metal-to-filler ratio, the proper outer plies, and uniform spot welds on the OD.
Inward buckling of spiral wound gaskets remains a concern in the industry. Various industry committees are actively working to improve standards to address this issue. Some end users avoid using inner rings due to cost or bore intrusion. To meet this need, We offer LS_AB style gasket.
The LS_RF style gasket shares the same construction features as a standard gasket but is specifically sized to serve as a replacement for flanges machined to accept oval or octagonal ring joint gaskets. The sealing element is positioned between the groove ID in the flange and the flange bore.
The LS_LE style gasket is the ideal choice when high density and low emissions are critical. This enhanced spiral wound design includes essential components such as a carbon steel guide ring and a stainless steel inner ring.
