Pressfit System


Pressfit System for Carbon Steel Pipe

The Pressfit System offers economy, speed and reliability for joining small diameter pipe for fire protection, heating/air conditioning and many other services.
Pressfit products for carbon steel pipe are externally zinc electroplated. Pressfit carbon steel is not intended for use in open loop water systems. Request 12.02.
The system incorporates Schedule 5 steel pipe from 3/4 - 2" (20 - 50 mm), with a system of Pressfit couplings, elbows, tees, reducers and adapters. This system allows pipe assembly in seconds. A portable, hand-held electricor hydraulic tool assembles the fitting on the pipe with a permanent mechanical attachment.
The Pressfit System for carbon steel is BOCA approved - HVAC (Cat. 23) and Fire Protection (Cat. 15). It is Listed by SBCCI PST and ESI in Report No. 9535.
Pressfit System products are rugged and reliable. They are UL/ ULC Listed and FM Approved for 175 PSI (1200 kPa) fire protection service and rated to 300 PSI (2065 kPa) for heating water and other general services.
Request PB-500 for complete Pressfit system details.

O-Ring - Precisely molded compresses against pipe O.D.
Housing - Precision formed externally zinc electroplated carbon steel with integral pipe stop
Pipe Stop - Assures uniform take-out dimension and positions pipe for proper assembly (not on Slip Coupling)
O-Ring Pocket - Sized to contain the O-ring, the pocket is deformed during assembly
Pressfit Tool Indent - Housing is uniformly compressed with the Pressfit Tool into a permanent mechanical engagement onto the pipe.
NOTE: Designers of systems exposed to potentially corrosive situations (high humidity, marine or process environments, etc.) should always consider use of protective coatings on any carbon steel piping products.

O-Ring Selection

Pressfit products with Grade "E" EPDM, Grade "T" nitrite or Grade "O" fluoroelastomer O-rings are available for many piping applications including compressed air, plant cooling water, welder water, chilled water, machine service piping, machine oil piping and solvent lines.
NOTE: Since the interior is not rubber lined, any applications involving substances corrosive to steel, but not corrosive to an O-ring may result in a premature system malfunction.
Designers of systems exposed to potentially corrosive situations (high humidity, marine or process environments,etc.) should always consider the use of protective coatings on any carbon steel piping components. Victaulic offers Pressfit fittings with external zinc electroplating and stainless steel Pressfit products. Contact Victaulic for details.
