1 System Data Sheet
ProPress 304 FKM is a stainless steel
system designed to be used with
Viega stainless steel pipe to form a
complete press system that is ideal
for industrial applications. ProPress
304 FKM 󶈵ttings utilize a versatile
FKM sealing element to provide a
permanent, leak-free connection in
dimensions from ½" to 4". A ProPress 304 FKM system can
stand up to harsh environments while transporting process
water, diesel fuel, lube oil, ammonia, low pressure steam, or
any number of other essential 󶈶uids.
ProPress 304 FKM 󶈵ttings are o󶈴ered in con󶈵gurations
including: elbows, couplings, reducers, tees, reducing tees,
threaded adapters, unions, caps, and 󶈶anges. ProPress
304 FKM 󶈵ttings in 2½" to 4" have a 420 stainless steel grip
ring and a PBT separator ring in addition to the FKM sealing
element.
