Parker Welding Hose is engineered for portable or production line welding in a variety of settings. Typical applications would be factories, ships, construction sites, steel mills and foundries. One of the staple Parker Welding Hoses is the Siameez hose. This is a Grade T Twin Line Welding Hose, where red is the fuel line and green is the oxygen line. Series 7109 is a premium twin line welding hose that is flame and oil resistant due to its tube and cover. The following fuels can be used with the Red line; acetylene, hydrogen, natural gas, propane, and propylene. The green line is compatible with oxygen. Grade T is the only grade that has been recognized for use with oxy-fuel gas welding applications by the Compressed Gas Association.
Grade T Single Line Welding Hose, Series 7141 (Red, Gas) and Series 7142 (Green, Oxygen) are premium single line welding hoses from Parker. These hoses feature flame and oil resistant tubes and covers. Naturally, only the red line can be used with fuel and only the green with oxygen. These hoses are made for a wide variety of applications and long continuous lengths are available. Typical applications include, bending, brazing, cutting, fabrication, gouging, joining, piercing, pre-heating, post-heating, severing, soldering, straightening, surfacing, and trimming. Typical places of use would be assembly and fabrication shops, construction, factories, foundries, mines, oil rigs, plumbing, rail yards, salvage, scrapyards, shipyards and steel mills.
Another option is the Siameez Series 7126 twin line welding hose. In this case the red line is compatible with acetylene only, and not any other type of fuel. The green line is compatible with oxygen, as per normal. As with the other hoses mentioned here, the tube is “non-blooming” which minimizes the migration of combustible waxes or plasticizers the rubbers surface. In addition, flexibility is provided for with plies of textile reinforcement.
Parker Water Hose offers plenty of variations of water hoses that can handle any water transport application you can throw at it. Parkers suction and delivery hoses are used in a variety of industries for all kinds of different applications.

Parker Steam Hose is built to withstand one of the most brutal applications hose is used for, where steam cycles hot, cold wet, and dry conditions both internally and externally on the rubber compounds that are used for its construction. One of the best examples of this is the Dragon Breath 250, series 7288. This is a traditional oil resistant hose that has been specifically designed by Parker to withstand the tough environment of the hot, cold wet, and dry cycle. The Dragon Breath 250 has an EPDM tube that helps prevent popcorning and heat resistance. This hose also features a wire braid reinforcement for prevention against crushing and to provide extended durability throughout its service life. This wire braid also creates a path to conduct a static electrical charge to ground. Lastly, this particular hose series 7288 is especially popular among oil refineries due to its red cover that is resistant to weathering and oil while providing color coding.
Another popular entry in the Parker Steam Hose category is the Steam-Lance 250, series 7264 (red). This hose has been designed as a traditional steam hose, built to withstand the hot, cold wet, dry condition cycle that steam applications impose. The EPDM tube, much like with the Dragon Breath 250, helps to resist popcorning and heat while adding a wire brain reinforcement for preventing crushing. The wire braid also adds kink resistance, and a red cover that is resistant to abrasion, cracking, hardening, and ozone.

Style numbers are the method Firestone uses to describe the form of the rubber and fabric bellows used in our air spring assemblies. This bellows style is the major contributor to the physical performance characteristics of the Firestone air spring assembly, and is the first piece of information necessary to identify a part in the field.
Molded into the sidewall of each Convoluted and 1T style Firestone bellows is a style number. It can take the form of up to three distinct groups of letters and numbers. First there may be a group of one to three letters, normally “K” or “AY”. This is a designation of the manufacturing entity. It is not important to your identification. Next will be a more familiar series of numbers and letters like 26C or 1T15M6. This is the style number. Finally there may be an additional letter like “E”. This is just a designation of the mold cavity that the part was cured in (in the case of “E” it would be the 5th mold cavity). Again, this is not important to your identification.
Now, we need to explain a bit more about the style number itself. A convoluted part will normally be a 2 or 3 digit number, perhaps with a “-” after it. However, after all of the numbers there will be a letter like B, C, D, etc. This is just a designation of the latest design iteration. In most cases this will not affect the performance of the part since it should meet the same performance criteria in order to keep the same style number. However, for complete-ness in communication it is usually best when calling in to tell Firestone this letter if you can read it. (i.e. 22B or 22C).
On the 1T style parts we need the whole character string (i.e. 1T15M-6). The 1T designates a heavy duty rolling part with a piston or pedestal on one end. The number after 1T refers to the basic family size of the part (i.e. 14, 15, 19, etc.) The next few letters give us specific performance characteristics, and finally the number after the “-” indicates the length of the part. This whole string is necessary to determine the style number.
