Features:
Certified to NSF®/ANSI 61-G.
Removable lugs to allow installation in tight spaces.
May be used to join plain end pipe of the same diameter.
18-8 Type 304 Stainless Steel band for corrosion resistance.
Standard widths 7.5” through 30” (product 221 is 5” standard).
A 360° gasket seal provides maximum support and reinforcement.
Lugs have a fusion bonded Flexi-Coat epoxy coating for corrosion resistance.
Repair or join pipes in a wide variety of sizes and widths to fit your application.
One starter (longer) bolt minimum per clamp thru 4.5” O.D. sizes to help with installation.
Range up to .40” in the single band (slightly less in smaller sizes); .80” in the double band; more
in larger clamps to help reduce inventory.
Drop-in bolts feature to ease installation. If more than one band, all joints except for one will have
all-closed lugs to keep bolts in place during installation.

*The allowable working pressure of a pipe repair clamp decreases as pipe diameter increases (regardless of manufacturer). For a particular installation, the allowable working pressure will be determined by the size of pipe, type of pipe, type of clamp, type and extent of damage, service conditions, environmental conditions, and installation workmanship.
Product Specifications
The full circle repair clamp shall have an
18-8 Type 304 stainless steel band. It shall
be a minimum of 7.5" in width (5" minimum
width for the 221). The lugs shall be made of
high strength ductile iron per ASTM A536
GR80-55-06 and have a fusion bonded Flexi
Coat epoxy coating.
The lugs shall be attached to the band by
hemming the band and sliding it into the lug
slot. The slot shall be cast into the lug base.
The lug shall have a friction fit with the band,
preventing it from sliding off, yet allowing for
easy removal and reattachment in case of
installing the clamp in restricted spaces.
The gasket shall be made of Nitrile
(Buna N) specially compounded to resist
water, oil, acids, alkalies, most (aliphatic)
hydrocarbon fluids, and many other chemicals.
The temperature range of the gasket
shall be -20ºF thru +180ºF. The gasket must
have a bridge plate that helps the end of the
clamp band to seal across the gap. The
bridge plate shall be made of quarter-hard
304 stainless steel. It shall be recessed and
bonded into the gasket. The gasket shall
have a gridded pattern. The gasket shall be
tapered on the ends and overlap for range
capability.
All bolts shall be at least 5/8" x 6" high
strength low alloy per ANSI A21.11 and
B18.10. At least one 5/8" x 6 7/8" bolt with a
taller nut shall be furnished to help facilitate
installation of clamps up thru 4.50" O.D.
Heavy semi-finished nuts meeting ASTM
A563 shall be provided with the bolts. Multiband
clamps shall have all closed lugs
except for one set of open and closed lugs
to allow for easy opening and installation of
the clamp.
OPTIONAL - Stainless steel type 304
bolts and nuts. The nuts shall be fluoropolymer
coated to prevent galling.
