Material Specification

JCM 408 Coated Service Saddle - Double Electro Galvanized Steel Straps

JCM Coated Saddles are constructed of ductile iron with a high density fusion plastic coating and have two electro galvanized steel straps, nuts and washers for high corrosion resistance.

Body Casting:

Wrap around design of Ductile Iron, ASTM A-536 annealed to 60-40-18. Body has a gasket cavity, which provides internal as well as external gasket retention.


Nitrile Butadiene Rubber (NBR, Buna-N) per ASTM D2000. Molded virgin rubber with a pressure activated hydromechanical design. Gasket is bonded into a cavity for internal and external retention. Gasket temperature range -40 o F to 212 o F (-40 o C – 100 o C) Gasket suitable for water, salt solutions, mild acids, bases, and sewage.


EPDM gasket available.


Nominal sizes 2" through 12" have corrosion resistant, forged AISI C-1018 steel straps, zinc plated with dichromate seal. Nominal sizes 14" through 24" have two (2) 2-1/2" wide fabricated steel straps for additional stability and strength coated for corrosion resistance. Casting is coated with fusion bonded high density blue plastic, 12 mils minimum thickness, with a dielectric strength of over 12,000 volts. Water absorption less than .20% (less than nylon) prevents undercutting and blistering.


Pressure Rating:

Working pressure is 250 PSI hydrostatic. Contact factory if higher working pressure is required.
