Hoses, Fittings and Accessories

Blast Hose:

Blast Hose is designed to transfer an air and abrasive mixture from the abrasive metering valve to the blast nozzle. It is made with a liner for abrasion resistance, fabric reinforcement for structural integrity and a protective cover. The cover of the blast hoses is made of a durable material that resists tearing, puncturing and aging from exposure to the sun.

Note: When choosing blast hose, remember these tips:
  • Blast Hose should be sized 3-4 times the nozzle size (i.e. ¼” nozzle should use a minimum of 3/4” I.D. Blast hose)
  • When using a whip section (10 or 12.5’ section), size the whip SUPA hose so the I.D. is the same as the I.D. on the regular blast hose (i.e. 1-1/4” I.D. Supa hose should be used with a 1-1/4” I.D. x 2-5/32” O.D. Blast Hose)
  • Blast Hose Safety cables should be used between all hose connections (i.e. pot to hose connection, hose to hose connection)
  • Blast hose ends should be cut square (use a hose cutter, available to purchase)
  • Couplings should be securely fitted on blast hose and sized properly to fit the blast hose.

4 Types of Abrasive hoses are available:

  • 4-Ply Blast Hose is used in industrial settings (Blast rooms, shipyards and railyards) where external scuffing and occasional light vehicle traffic is expected. Has an inner tube wall of ¼” thick SBR rubber treated with static-dissipating compound. (Black, Black/yellow or Black/green)
  • 2-Ply Blast Hose is more flexible than 4-ply hose but more durable than the SUPA or super-flex hose. Inner tube is 5/16” Thick SBR rubber with a static-dissipating compound. (Green in color)
  • SUPA Blast hose is the most flexible and lightweight of the blast hoses. It has a slightly thinner outer casing than the 4-ply and 2-ply hoses and is made from SBR rubber. Primarily used to add a “whip” section to your blast hose allowing the operator to hold a lightweight hose at the end while maintaining a thick hose most of the distance to convey the material. Available in ¾” I.D., 1” I.D. and 1-1/4” I.D. sizes to be used as a whip with the same I.D. sized 4-ply or 2-ply blast hose.
  • Extreme-Duty or Survivor® Blast hose is a 4-ply blast hose with a 5/16” thick liner and treated with a compound to increase the service life up to 150% over the standard blast hose. It is the longest lasting blast hose on the market for use in the most extreme conditions.

Twinline Control Hoses:

Metal Finishing maintains a stock of twinline control hoses for most manufactures of blast equipment. The proper hose twinline should be used with each type of equipment and substitute hose should not be used for safety reasons (1/4” welding line, etc.). The proper fittings should be used also with each type of system. Twinline is available in 5’, 16’ 25’, 50, 55’ or 110’ premade sections. Bulk twinline and fittings are also available.

    Couplings & Fittings:

    The proper hose fittings should be used given the type of hose in use and should be checked daily for wear and replaced as necessary. Gaskets in couplings should be replaced often and hoses should be installed tightly on or in their respective fitting to prevent premature failure of the hose, nozzle or coupling.

They are available in number of materials including Aluminum, Nylon, Brass and Iron/Steel and usually have corresponding references based on size. Couplings are available in standard port or full-port opening sizes for production blasting. (Note: Full port couplings will not couple to standard port couplings).
