Vacuum Components

KF Clamps:

Descriptions:

ISO-KF vacuum clamp fittings (sizes KF-10 to KF-50) conform to standard NW dimensions (NW-10 to NW-50). Crafted from durable aluminum, these “quick flange” components allow for rapid assembly in line vacuum plumbing and process systems. The secure vacuum seal is achieved using a circumferential clamp paired with a centering ring that houses a rubber elastomer O-ring.

TC clamps:

Descriptions:

Tri-Clamp (TC) fittings quickly secure sanitary tube connections ranging from 1/2″ to 2″+. Built from high-grade stainless steel, these components provide reliable joints for process lines in the food, beverage, and Pharmaceutical industries. A leak-proof seal requires a compatible gasket (sold separately). To install, hand-tighten the wing nut until snug, then rotate it an additional half to full turn. Avoid overtightening, as excess torque does not improve performance and can damage the gasket or flange.

ISO-K Double Claw Clamp:

Descriptions:

Aluminum double-claw clamps rapidly secure ISO-K (DN 63 to DN 100) vacuum flanges in any orientation. Conforming to DIN 28404 and ISO 1609 standards, these heavy-duty clamps hook directly into the ridged outer groove of the flange face. A leak-tight vacuum seal requires an elastomeric O-ring centering ring placed between the mating surfaces. While large ISO-LF standards span sizes from DN 63 to DN 1000, these specific aluminum claw clamps are optimized for DN 63, DN 80, and DN 100 industrial process vacuum plumbing systems

KF Centering’s and o rings:

Descriptions:

Stainless steel (size KF-16 to KF-50) centering rings feature a chemical-resistant Viton O-ring to deliver a secure vacuum seal for NW-16 quick-flange systems. Built to ISO-KF standards, these corrosion-resistant assemblies are engineered for rapid installation in process line vacuum plumbing. The leak-tight seal is achieved when a circumferential clamp compresses the elastomeric O-ring between the mating flanges. This configuration leverages Viton’s exceptional thermal stability, safely operating at continuous temperatures up to 200°C.

KF Blank Flange:

Descriptions:

stainless steel ISO-KF blank flanges block off unused ports in line vacuum plumbing and process systems. These quick-assemble fittings conform to standard NW dimensions, with a size range spanning KF-10 to KF-50 (NW-10 to NW-50). A leak-tight vacuum seal is formed by compressing an elastomeric O-ring centering ring between the blank and the mating flange using a circumferential clamp.

ISO KF short and Long Weld Stub and KF flanges nipples:

Descriptions:

stainless steel ISO-KF long-weld stub half-nipples allow for permanent weld connections in line vacuum plumbing and process systems. These quick-assemble components adapt welded tubing to standard NW dimensions, spanning sizes KF-10 to KF-50 (NW-10 to NW-50). A reliable vacuum seal is achieved by securing the mating flanges with a circumferential clamp and an elastomeric O-ring centering ring.

Adapters:

  1. KF to Thread adapter:

Descriptions:

stainless steel ISO-KF adapters bridge the gap between quick-flange vacuum lines and threaded pipe systems. Available in both male and female NPT and BSP configurations, these adapters span standard sizes from KF-10 to KF-50 (NW-10 to NW-50). The vacuum side fastens quickly using a standard circumferential clamp and elastomeric O-ring centering ring, enabling reliable transitions to industrial process plumbing.

2. KF to CF adapter:

Descriptions:

stainless steel ISO-KF to CF adapters connect quick-flange components to ultra-high vacuum systems. The ISO-KF side spans standard sizes from KF-10 to KF-50 (NW-10 to NW-50) and seals rapidly using a circumferential clamp and an elastomeric O-ring centering ring. This allows seamless transitions from high-vacuum O-ring systems to all-metal, knife-edge CF flange configurations.

3. KF to ISO adapter:

Descriptions:

stainless steel ISO-KF to ISO-LF adapters bridge small-diameter quick-flange lines and large-flange vacuum systems. The KF side spans sizes from KF-10 to KF-50 (NW-10 to NW-50) and utilizes a circumferential clamp and elastomeric O-ring centering ring for rapid assembly. This allows for a smooth, standard-compliant transition to larger ISO-LF industrial process plumbing.

4. KF to Hose nipple:

Descriptions:

ISO-KF to rubber hose adapters connect quick-flange vacuum lines directly to flexible rubber hoses with internal diameters (ID) ranging from 7/16″ to 5/8″. The vacuum side spans standard sizes from KF-10 to KF-50 (NW-10 to NW-50) and seals rapidly using a circumferential clamp and an elastomeric O-ring centering ring. Available in both lightweight aluminum and corrosion-resistant stainless steel, these adapters provide a reliable transition from rigid process plumbing to flexible lines.

5. KF to Swagelok adapter:

Descriptions:

Stainless steel KF-25 to 3/8″ Swagelok adapters seamlessly connect standard NW-25 quick-flange components to compression-tube fittings. The ISO-KF side fastens rapidly using a standard circumferential clamp and an elastomeric O-ring centering ring to ensure a reliable vacuum seal. While general quick-flange systems span sizes from KF-10 to KF-50, this specific adapter provides a rugged, leak-tight transition from NW-25 process lines to 3/8″ Swagelok instrumentation tubing.

KF Reducers:

Descriptions:

stainless steel ISO-KF conical and straight reducers seamlessly transition between different line diameters in vacuum plumbing and process systems. These quick-assemble fittings allow for smooth flow reduction across standard NW sizes ranging from KF-10 to KF-50 (NW-10 to NW-50). A leak-tight vacuum seal is maintained at each junction by securing the mating flanges with standard circumferential clamps and elastomeric O-ring centering rings.

Bellows:

Descriptions:

These ISO-KF standard flexible metal hose bellows are designed for line vacuum plumbing and process systems. Each bellow features tag-welded end flanges that undergo helium leak testing to guarantee leak-proof performance. Often called “quick flange” fittings, they assemble rapidly using a circumferential clamp and a centering ring fitted with a rubber elastomer O-ring to form a secure vacuum seal. Built from corrosion-resistant stainless steel, these versatile components are available in standard KF, ISO, and CF end flange configurations, as well as custom combinations.

KF tee cross and elbow :

ELBOWS:

These ISO-KF standard 90-degree elbow vacuum fittings are designed for directional changes in line vacuum plumbing and process systems. Often called “quick flange” fittings due to their rapid assembly, they use a circumferential clamp and a rubber elastomer O-ring centering ring to form a reliable vacuum seal. Built from corrosion-resistant stainless steel, these elbows are available in standard industry sizes from KF-10 to KF-50 (corresponding to flange sizes NW-10 through NW-50).

Cross 4-Way:

These ISO-KF standard 4-way cross vacuum fittings are engineered for multi-directional intersections in line vacuum plumbing and process systems. Commonly known as “quick flange” fittings for their rapid, tool-free assembly, they utilize a circumferential clamp and a rubber elastomer O-ring centering ring to establish a secure vacuum seal. Fabricated from corrosion-resistant stainless steel, these 4-way crosses are available in standard industry sizes ranging from KF-10 to KF-50 (matching flange sizes NW-10 through NW-50)
