-【Various models】We also provide a variety of other types of schlenk flask to meet your different needs..

This non-portable water expansion tank is for closed loop hydronic heating system piping to control the thermal expansion of hot water and maintain system pressure below the relief sett of the relief valve.
The carbon steel tank is pre-charged at 12 psi, has a 4.5 gallon volume, and features a durable expansion membrane preventing minimizes loss of the air change and ensures long and trouble-free life for the system.
Made of carbon steel with epoxy finish, mounts to supply piping, with 1/2 inch MNPT system connection and .302-32 inch charging valve connection for on-site charging of the tank.
Maximum pressure 60 psi and can be used in residential or commercial hydronic heating systems.
Use in tandem with your hot water heater to absorb increased water volume ensuring long and trouble-free life for the system.

Reduces incoming water pressure to protect plumbing systems and reduce water consumption in commercial industrial and residential applications.
Suitable for up to 400 psi (27.6 bar), the pressure range can be adjusted from 25 to 75 psi (172 to 517 kPa) with the standard setting at 50 psi (345 kPa).
double union solder inlet and outlet connection.
integral stainless-steel strainer (removeable for cleaning).
bypass feature that controls thermal expansion pressure.
and a sealed spring cage for waterworks pit installations.
Offers easy installation, easy handling and in-line serviceability.
The standard bypass feature permits the flow of water back through the valve into the main when pressures, due to thermal expansion on the outlet side of the valve, exceed the pressure in the main supply.

Used to seal out dust, air, wind-driven snow, and moisture through joint details in metal buildings and similar structures, both pre-manufactured and site-built..
will not dry out and become hard and brittle.
seals gaps susceptible to mildew and vermin..
will not extrude from between joints like caulk or butyl-tapes.
maintains a seal during thermal expansion and contraction of building panels.
no shrinkage or blow-out due to closed-cell breakage..
Supplied with adhesive on one side. After removal of packaging, begins gradual expansion, more slowly in cold weather than in hot..
