Discover H-P's offers a variety of couplings for tube and pipe joining. Including INSTALOK™, Vac-Lite™ Core, and standard 2-Bolt & 3-Bolt compression couplings, clamps, and more.
INSTALOK™ Coupling
Designed specifically for conveying plastic pellets and for other non-sanitary vacuum applications.
- Offered in 1.5” through 4” sizes.
 - Galvanized steel construction, with O-rings available in Black Nitrile, White Nitrile, or Viton™.
 - Eliminates the risk of product contamination due to deteriorating gasket material.
 - Installs in half the time of competing couplings, while delivering superior performance.
 - Costs 20% less than traditional compression couplings.

Vac-Lite™ Core Coupling
Core performance. Everyday value.
Our lightweight, cost-effective coupling designed for industrial vacuum (IVAC) applications. Engineered with simplicity and durability in mind, it offers a secure fit for everyday applications without the bulk — making it the go-to choice for performance and value in system essentials.
- Offered in 2.125” through 6.625” sizes.
 - 430 Stainless Steel construction with grounding strip.
 - White silicone gaskets (standard).
 - Lightweight design for easier handling and installation.
 - Delivers a dependable seal for day-to-day industrial vacuum performance.
 
Vac-Lite™ Core Coupling installation instructions available here.
Compression Coupling
Designed for vacuum and pressure applications in pneumatic conveying or industrial vacuum systems.
- Offered in 1.5” through 14” sizes.
 - Heavy-gauge, zinc-plated steel construction.
 - Stainless steel grounding strips (to eliminate static electricity build-up) are standard, and gasket protectors (to eliminate gasket wear) are available.
 - Standard gaskets are made of Black Neoprene or White Nitrile Rubber. Also available are Silicone, Red Rubber, EPDM, and Viton™.
 - Stainless steel couplings are available upon request.

Eliminator
Designed for higher-pressure applications and anywhere else superior holding power is needed.
- Offered in 2” through 12.75” sizes.
 - Construction is similar to the compression coupling, with two additional bands to add metal-to-metal gripping power.
 - Conversion kits are available to retrofit a standard compression coupling into an eliminator.
 
Super Grip
Designed as a quick coupler for dry, bulk transport tank tubing and applications involving the teardown of lines for periodic cleaning.
- Offered in 1.5” through 12.75” sizes.
 - Type 430 bright-annealed stainless steel construction allows it to survive harsh weather or road conditions.
 - Available in single or double clamp configurations, providing fail-safe clamping action despite expansion, contraction, and vibration.
 - FDA-approved gum rubber gaskets come standard for use in food applications.
 - Provides better support than rubber hose and band clamps.
 
Aluminum Cam & Groove Couplings (quick-acting)
Designed for non-permanent connections, such as hose to equipment.
- Offered in 1.5” through 8” sizes.
 - Female couplers are supplied with a locking feature. Safety clips may be inserted to lock the handles, preventing disconnection during product transfer. Brass security chains are available.
 - Stainless couplings are available.
 - All sizes except 5” and 8” are covered by MIL Spec A-A-59326.
 - Compliance with this specification allows for brand interchangeability
