VISEGRIP II Plug, Flange and Cap Seal Closure System

Fundamental to the Rieke drum closure line is the design of the VISEGRIP II—the strongest, most dependable closure to seal a drum.

The flange has a series of serrations that lock into the drum material upon insertion.

When the plug is torqued into the flange, it seals at the most critical point—the flat surface of the drum head—in effect tightening the plug and gasket in a vise-like grip. A cap seal can then be added for additional protection against tampering.

Synthetic Plugs - VISEGRIP II®

PPN Fusible Closures
The unique design of Rieke Packaging Systems’ PPN series makes it the ideal closure for drums containing combustible materials. Its reinforced nylon material provides a reliable seal, but when exposed to extreme heat, melts away in the center of the closure to allow volatile gases to vent, thus reducing the risk of explosion.

VISEGRIP Fusible Closures Series:

• Meets UN Packing Group I, II, and III performance requirements with elastomeric gaskets.
• Meets UN Packing Group II and III performance requirements with polyirradiated gaskets.
• Features a nylon materialIs Factory Mutual approved to meet protection guidelines in NFPA 30, chapter 4, sections 4-8.

DANGER:
The end user is strongly advised to store drums in an upright position at all times. The end user is warned to keep a safe distance from a drum that is in a fire or subject to very high heat.

Note: All models incorporate a chemically resistant polypropylene and/or polyethylene material unless otherwise indicated.

Vented Closures

Specialty Steel Electro-Zinc Plated/Yellow Chromate Finish
Rieke Packaging Systems offers several pressure relief plugs forged out of heavy gauge steel for exceptional material strength.

S-220-2 PRESSURE RELIEVING PLUG
While applying the distinctive sealing qualities of the fundamental VISEGRIP, Rieke’s S-220-2 also serves as thedrum’s relief valve for packaged hazardous materials.

• Prevents buildup of internal pressures by venting volatile gases.
• Vents at internal pressures of 13 to 15 psi.
• Reseals at approximately 8 psi.
• Plugs with different venting pressures are available.

Note: To ensure proper operation, this plug must be chemically compatible with—and located above the liquid level of - the drum contents.

Steel Flanges - VISEGRIP II®

Flanges
The VISEGRIP steel flange features a unique design which permits it to become an inseparable part of the drum head. A key to the effectiveness of the VISEGRIP flange is a series of serrations that lock it into the drum metal when inserted. The VISEGRIP II is designed with the drumstock having a circular emboss around the 2” flange for easy identification. A radial seal of the drum stock to the plug gasket sets the VISEGRIP II apart from other closures.

Standard VISEGRIP II flanges:

• Are constructed of a heavy-gauge steel.
• Feature NPS pipe threading.
• Yellow chromate finish, but are also available in unplated steel, or lined with commercial coatings.

Micro-Porous Vents

Many of Rieke Packaging Systems’ plastic closures can be equipped with a Micro-Porous Gauze Vent that allows two-way venting for either pressure or vacuum relief. Chemical manufacturers appreciate the design capabilities of Rieke Packaging Systems’ reversible vents. Formulated with two special synthetic materials (Buna and EPDM), these vents meet compatibility requirements while accommodating pressure and/or vacuum relief.

WHEN USING THESE VENTS:

• Be sure to allow for adequate head space in the container.Failure to do so can plug the vent or cause leakage.
• The container should be transported and stored in an upright position.
