Features:

IDEAL® Clamps
1/2" and 9/16" band widths with 5/16" hex-head screw applies 60 in.- lbs. of installation torque to the band/shield assembly.

Patented Bi-directional Shield Design
Our unique shield design employs bi-directional corrugations for maximum transfer of pressure from the clamps to the gasket. This patented* shield design adjusts to differences in the circumference and outside diameters of the pipes being joined. This eliminates gasket wrinkling and thereby eliminates leak paths. These bi-directional corrugations also create sealing pressure in both parallel and transverse patterns on the gasket and pipe. This works to avoid “pull out” failures and provides a positive, reliable seal.

Specially Beaded Gaskets
The IDEAL® standard no-hub coupling utilizes a specially beaded gasket that combines with the shield and clamping forces for superior sealing pressure and holding power.

Floating Eyelet Design
Floating eyelets fasten the clamps to the shield, allowing the clamp band and shield to move independently. This freedom prevents the shield from crimping during tightening, which can lead to leakage later on.

Mechanical Interlocking Clamp Design
IDEAL® clamps feature a one-piece screw housing that mechanically interlocks the housing to the band. This one-piece housing design eliminates leak paths that can occur in staked or welded clamps.

*U.S. Patent No. 5,431,458 

Description:
Couplings consist of gasket and shield assemblies. The shield assemblies have two to four clamps depending on the size. The clamps are fastened with eyelets to the bi-directional corrugated shield. Materials: Steels used in couplings are stainless steels. Shields, bands and housings are AISI 301. Screws and eyelets are AISI 305. Gaskets are made from an elastomeric compound that meets the requirements of ASTM C564.

Specifications:
Couplings conform to CISPI 310. Couplings comply with ASTM C564, ASTM C1277, IAPMO file #3198, Commonwealth of Massachusetts CMR-248 and City of New York MEA 253-98-E. Gaskets are made from an elastomeric compound that meets the requirements of ASTM C564.
