Metal Expansion Joints

Metragator Metal Expansion Joint

The Metragator comes standard for movements of 4″, 6″ and 8″.  Available in 150 and 300 psi models and can be configured as doubles if required. Consult factory if doubles are required.

Other sizes and types are available up to 24″. Learn more on other Metraflex Metal Expansion Joint options.

Rubber Expansion Joints

The Metrasphere is most commonly used as a pump or equipment connector.

• Reduce noise and vibration
• Reduce pipe stress on your system
• Handles movement in all directions
• Self Cleaning

Metraloop Joints

The typical Metraloop installation is axial for thermal applications, or in any possible direction for seismic applications – including axial, lateral and angular.  Piping systems are used to convey hot water, chilled water, steam, condensate, potable water, fire sprinkler lines, gas lines, waste lines, and more.

Metraflex Energy Saving Pump Connectors

Vane Flex

• Reduces discharge turbulence in a fraction of space
• Hydrodynamic shaped vanes
• Protects valves immediately downstream of pump
• Equals 5-10 pipe diameter turbulence reduction
• Less Pressure drop than 5-10 pipe diameter
• Vibration isolating pump connector

Suction Diffuser Flex

• Guaranteed measurable improved performance
• Reduced pump vibration and wear
• Maximize pump operating life
• Reduced pump maintenance
• Increased pump efficiency
• Increased flow rate

VRF Expansion Joints

• Higher Operating Pressures: VRF/VRV systems operate at significantly higher pressures than traditional hydronic systems
• Extreme Test Pressures: Can reach up to 700 psi
• High Operating Temperatures: Ranges from 200°F to 300°F
• Increased Stress Levels: Operates at the high end of piping component limits
• Requires Additional Design Considerations: Due to higher pressures and temperatures, careful system design is essential

Metraflex Compensators

• Externally pressurized expansion joints with 3″- 4″ of compensation and .5″ of extension.
• Allows 2″ – 3″ of compression and .5′ of extension on various options.
• Features nickel-plated internal guides for quiet operation.
• Rugged design protects the bellows.
• Available in .75″ through 3″ – 4″ diameter in flanged or weld ends.

Metraflex Strainers

• Increase equipment performance, remove debris
• Designed for straight, smooth flow
• Maximize pump life from iron oxide build-up
• 2″ – 16″ at 125 psi
• Steam options up to 400°F and up to 250 psi

Metraflex Wall Penetration Seals

Metraflex Wall Penetration Seals create a mechanical water-tight seal, filling the space around any round pipe including: concrete, steel, plastic, cast iron, copper, and electrical conduit.

• Mechanical, interlocking rubber waterstop
• Rated at 20 psi
• Helps isolate noise and vibration
• EPDM, Nitrile and Silicone options

To quickly calculate the right seal for your application use the online seal calculator.

Metraflex Pipe Guide Anchors

• Available in sizes up to 24″
• provides lateral restraint of a piping system, allowing the pipe designer to control pipe movement and prevent bowing or buckling of the piping system.
• Various styles and options for steel or copper pipe.
