Mini Fittings

Miniature hose barb fittings feature raised ridges, called barbs, that grip the inside diameter of a tube to create an airtight seal. Versatile and easily installed through a push connection, miniature barb fittings are used in many industries, including food and beverage, medical, dental, semiconductor, pharmaceuticals, and others.

Straight Barb Fittings

Miniature straight barb fittings are suitable for pneumatic systems in confined areas as they can connect lines without the extra space required by standard hose barb fittings. We maintain a large inventory of straight miniature hose barb fittings to meet the needs of any pneumatic system, including hose barb-to-male thread or hose barb-to-female thread options. Standard, M4, M7, and M10 threads are currently stocked with SAE threads also available.

Elbow Barb Fittings

Typically used in small or handheld products, miniature elbow barb fittings effectively connect air lines in systems with space restrictions. Polyconn’s inventory offers options with M3 or M5 bolt threads as well as barb-to-male thread and barb-to-female thread options to match your pneumatic operation’s requirements.

Bulkhead Hose Barb Fittings

Miniature bulkhead hose barb fittings create a tighter grip and seal for high-pressure pneumatic systems. While most of our bulkhead barb fittings are made from metal, PEEK options are available upon request. Specifications include:
  • ID from 1/16” to 0.170”, depending on model
  • Buna-N O-Ring
  • Thread sizes from 10-32 to 5/16-24
We also offer tee barb-to-barb fittings for high-pressure applications requiring three lines to be joined.

Tee Barb Fittings

Featuring an O-Ring made from Buna-N and available in several sizes to meet the demands of any pneumatic system, miniature tee barb fittings feature a cylindrical design and are applied to join several pneumatic tubes. They have a UNF 10-32 thread and varying internal diameters.

Thread Fittings

Thread fittings are used mainly for small pipe diameters whose  nominal diameter is NPS 2 or smaller.
