Pipe Penetration Seals
AD Muller2020-08-24T19:10:07+00:00Pipe Penetration Seals
The Pipe Penetration Seal is designed to provide a gas and water-tight seal. Pipe Penetration Seals PTFE Lined are Rubber Expansion Joints are lined with Teflon for corrosive chemical applications. Pipe Penetration Seals PEN-SEAL Pipe Penetration Seals have been designed to assist in achieving an efficient, low-cost mechanical seal between any Electrical Conduit, Concrete, Cast Iron, Steel, Copper, or PVC/CPVC pipes passing through Walls, Floors, Tanks, Pipeline Casings, and Vaults. The PEN-SEAL, while being used to seal the gap in electrical conduit lines, will also act as an insulator. The PEN-SEAL has been designed to provide a gas and watertight seal. All sizes have been tested to withstand a hydrostatic seal up to 20 psig or 40 feet of head pressure in addition to withstanding temperatures up to 250° F.
PEN-SEAL’s standard elastomer material is EPDM, which is suitable for temperatures ranging from -40° F to 250° F. EPDM is suitable for most applications in water—above ground and direct burial—and will provide the electrical insulation where cathodic protection is required. Silicone material is also available for higher temperature applications up to 400° F. Where the PEN-SEAL may come in contact with Hydrocarbons, Oil, Gas, Jet Fuel, and miscellaneous solvents, a Nitrile material is available with temperatures ranging from -40° F to 210° F. The PEN-SEAL utilizes glass-reinforced plastic for the pressure plates and all hardware is manufactured from Steel Zinc Dichromate. For corrosion resistance, 316 Stainless Steel hardware is also available. Various applications for the PEN-SEAL:
- Wall Sleeves • Precast Concrete • Valve PitsFloor Sleeves • Mining • Offshore Oil Platforms
- Interior Piping • Marine • Telecommunications
- Noise Dampener • Water & Wastewater • Dual Containment Seal
- Electrical Contractors • HVAC • Underground Steel Tanks
- Coal Preparation Plants
- Pulp & Paper
- Power Generation

Each Series 300 Flanged Rubber Pipe Connector is specifically engineered for your particular application. Multiple plies of tough fabric and helical spring steel wire are embedded into the pipe wall during the manufacturing process, resulting in a product precisely designed for your pressure and vacuum requirements.
Available styles include:
The Style 310 is precision molded to specific lengths, as listed in Table 3. The built-in rubber flanges are manufactured to adhere to ANSI 125/150# drilling specifications.
Style 310
The Style 310 is manufactured using conventional methods which allow for fabrication to a specific custom length requirement. It is also available in pre-manufactured lengths (shown in Table 3). The Style 310 is standard with 125/150# drilling, but can also be fabricated to meet other drilling patterns.
Style 320
The Style 320 is designed for high-pressure applications and is manufactured similarly to Style 310. Flanges are usually produced to ANSI 250/300# drilling specifications, but other drilling patterns can be accommodated upon request.
Some notable features of the Series 300 Flanged Rubber Pipe Connectors include:
The 9013-EP Low Torque Gasket is fully molded for precise sizing, and is manufactured with the PTFE film bonded to the EPDM rubber gasket. A unique outer sealing ring around each bolt hole is added, for additional sealing safety.
These special gaskets are for use on plastic, fiberglass, glass or other piping systems which require minimal sealing forces. The outer sealing rings provide the utmost in sealing at extremely low bolt torques.
Some notable features of the Series 9013-EP include:
The Series 450 Rubber Sleeve Type Pipe Connectors are constructed of neoprene rubber, and reinforced with impregnated woven nylon. Sealing beads are molded on the interior of the sleeve to provide extra sealing action for the clamping area. Internal reinforcing rings prevent deformation of the connector during surges or temporary negative pressure conditions. Outer reinforcement rings are added to provide even more external reinforcement.
Some notable features of the Series 450 include:
Dannenbaum LLC can supply a large range of rubber expansion joints.
Braided Flexible Metal Connectors

Metal Pump Connectors
Braided Flexible Metal Pump Connectors help with stresses that can occur within piping systems. Our flexible pipe connectors are constructed out of metal. Therefore, they have the ability to withstand high levels of pressure due to the braided metal which surrounds them. The connectors are suitable for many different mechanical applications for example, pipes, pumps, compressors and other heavy equipment.
Ordinary flexible metal hoses can fail to operate properly when subjected to high pressures; adding a flexible restraint, such as a metal braid, allows the hose to adequately withstand the specified internal pressure. As well as prevents elongation. The woven metal braid fits over the metal hose. It is also strong enough to withstand elongation up to the full pressure rating of the hose. Flexible hoses and braids are made from different metals. Common materials used for braided flexible metal connectors are 321 stainless steel hose and a 304 stainless steel.
Braided Flexible Metal Pump Connector
Braided flexible metal pump connectors control vibration, reduce noise, relieve stress, prevent system shock. Additionally, they compensate for misalignment and movement. Braided metal connectors such as pumps, compressors, and other mechanical equipment will help the overall operation of the system.
Flexible metal hose by itself, when subjected to high pressure can over-extend past the ability to operate properly. Therefore, include an external flexible restraint (i.e., braid) to withstand the specified internal pressure and prevent excessive elongation. A woven material known as braid is designed to fit snugly over the metal hose, it is fastened to the ends of both hose and fittings.
