King Nipples & Ferrules

Rubber Hose

Overview

King Nipples & Ferrules are essential fittings used in fluid handling systems, designed to create secure connections between hoses and equipment. These components are manufactured to precise specifications, ensuring reliable performance in demanding applications across various industries.

Key Uses & Applications

Water Suction & Discharge

  • Irrigation, dewatering, and general fluid transfer. Commonly seen on construction sites or farms where robust hose connections are needed.

Petroleum & Chemical Transfer

  • Suitable for low- to medium-pressure oil and chemical hoses. Typically used in fuel delivery, tanker truck lines, and industrial chemical handling.

Mining & Quarry Operations

  • Durable connections for high-volume slurry or water transfer. Maintain a tight seal even in harsh, abrasive environments.

Marine & Dredging

  • Connect large-diameter hoses for dredging sediment or pumping water in marine projects. Resilient design handles exposure to saltwater.

Product Highlights

Rugged Construction

  • Typically manufactured from carbon steel or stainless steel, designed to handle high vibration, moderate pressure, and rough handling.

Versatile Connection

  • Suited for clamp-style attachments, widely compatible with standard band clamps, bolt clamps, or crimp ferrules. Nipple ends often feature tapered pipe threads (NPT) or beaded ends.

Secure Grip

  • Ferrules provide a strong compression fit around the hose. King Nipples feature serrated or barbed shanks that help prevent hose slippage.

Multiple Finishes

  • Options may include zinc plating, galvanization, or plain steel. Corrosion-resistant coatings extend the service life in challenging environments.

Wide Size Range

  • Available in diameters from 2" to 12", accommodating heavy-duty large-bore hoses.
