Bazooka VT Vacuum Transducers with Funnel

Vacuum Removal Solutions for Loose Slugs, Shavings, Piercings or Finished Parts in Progressive Fabricating Dies

• Vacuum Sleeves
• Vacuum Transducer Funnel Units
• Vacuum Transducer Cap Units

Vacuum is applied to the die opening causing atmosphere air to flow through the die opening, preventing loose scrap from pulling out with the punch.

The Vacuum Transducer and Funnel are used to vacuum away loose scrap from multiple die openings.

The Vacuum Sleeve is installed beneath the die opening and prevents shavings from pulling up with the punch.


Compressed Air Distribution Systems

Clean Air & Optimal Efficiency

• Aluminium pipe ensures a total absence of corrosion

• Aluminium pipes prevent problems caused by rust
  common in metal pipe systems

• The “fullbore” design and the low friction coefficient of
   aluminium pipe provide optimal and constant flow
   throughout and minimize pressure drop

• Due to consistent clean quality air from the
  compressor to the equipment, aluminium pipe ensures
  higher longevity of the equipment and avoids frequent
  changes of filtration elements

Silicon Carbide Grease Mix

LOCTITE® Clover® Silicon Carbide Grease Mix abrasive pastes are the preferred abrasives for fast cutting all but the hardest and toughest metals. The result is a smooth flat surface. LOCTITE® Clover® Silicon Carbide Grease Mix is the most widely used. It retains the texture and lubrication properties during extended lapping. Typical applications include lapping, honing and grinding valve seats, gear teeth, dowel holes in dies, bushings, flat surfaces on seals and castings, machining parts, shafts, knives and cutting blades.

Sealing Solutions - O'Rings

Sealing Solutions – O'Rings

We carry O-Rings that can seal extremely high pressures in many applications.

We can customize O-Rings to facilitate sizes outside the standard requirements.

Our line-up is extensive:

• Aflas (TFE). These units offer an advantageous blend of high-temperature, chemical, and electrical resistance.

• Backup. Washer-style components that prevent seals from extruding through gaps when under pressure.

• Buna (Nitrile). These O-rings resist many fluids, plus abrasion and tear. High tensile strength, high elongation, and low compression set.

• Custom vulcanized. Tailored to specific application requirements.

• EDPM (ethylene propylene). O-rings with high tensile strength, elongation, high low-temperature flexibility, and good heat aging.

• HSN-80. These are better than NBR in low-brittle temperature, oil, and heat, with high resistance to sour gasoline and ozone.

• Kalrez. Units that resist more than 1,800 chemicals, with high-temperature stability.

• Metallic. These prevent gas or liquid leaks under adverse sealing conditions.

• PTFE-encapsulated. O-rings for harsh sealing environments, decreasing downtime wherever corrosive liquids or gases can result in premature seal failure.

• Quad-rings. Great sealing characteristics for many tasks.

• Silicone. Components with high resistance to temperature extremes and dry heat.

• Teflon. These are perfect for high temperatures or corrosive fluids or gases. Impervious to harsh chemicals, acid, and gases. Designed according to military specifications.

• Viton (fluorocarbon). O-rings with high-temperature stability. Resistance against chemicals, petroleum, weathering, ozone, and oxygen.

Shaft Repair Sleeves

 Shaft Repair Sleeves

These are precision stainless steel wear sleeves designed to prolong the life of damaged shafts and yokes by providing a new sealing surface that is superior to most original finishes and materials.
