This heavy design utilizes a broad cross section, hydro-mechanical outlet gasket in lieu of the full body gasket. This outlet gasket provides a positive seal, which improves with an increase in line pressure. The 452 has been engineered for installations requiring higher working pressure, higher safety precautions, or longer service life than standard all stainless or cast iron sleeves; and is manufactured to provide superior corrosion resistance applications on mains, which are not subject to beam breaks.
All Stainless Construction - All stainless steel construction provides extra corrosion resistance. The stainless steel flange, outlet, and body join as one unit of similar metals, to assure the highest structural strength and long-term corrosion resistance. Heavy Duty Design: Heavier construction and thicker metal provide extra reinforcement of the pipe and outlet. The extra bolting power and body thickness eliminate problems inherent with lightweight sleeves.
High Pressure Capability - Exceptionally Safe - The broad, heavy, hydro-mechanical gasket provides for high-working pressure applications. They are also ideal for critical problem prone taps such as pump stations, large diameter mains, and large outlets.
Large Sizes - High Pressure -The premier sleeve for larger sizes of ductile iron, PVC, PE and steel pipe. High-pressure sleeves are available on request.
Stronger - Yet Lighter Than Cast Sleeves - Reduced weight aids in installation and handling as well as reducing load on the pipe.
Extra Wide for Support and Stability - Extra width, and heavier neck and body material, provide extra reinforcement of the outlet, and extra stability during the tapping process.
Affordable - These all stainless sleeves are surprisingly affordable in all sizes. Larger sleeves are priced less than ductile iron mechanical joint sleeves which offer less corrosion resistance and pressure capability.
The 452 All Stainless Steel Tapping Sleeve is especially recommended for applications involving large diameters, high working pressures, and fluctuating line pressures in corrosive or acidic environments. Direct compression of the gasket provides maximum sealing capability for high or fluctuating pressures.
452 All Stainless Steel Tapping Sleeve - Typical Specification
Tapping Sleeve shall be of the high-pressure type, having a wide body, made of corrosion resistant 304 stainless steel, which conforms to, and reinforces the pipe. The sleeves shall have a Buna-N gasket with a hydro-mechanical activated lip, captured in a recessed groove around the outlet, replaceable stainless steel bolts (18-8 type 304), nuts, and washers. Stainless tapping sleeve shall be furnished with a 3/4" stainless steel test plug in the test outlet. Flanged outlets shall be indexed per MSS-SP60 to accept tapping valve. Tapping sleeve shall be ANSI/NSF Standard 61 Certified. Tapping Sleeve shall be 452 or an approved equivalent.
