How to Order Hose Assemblies

How to Measure Lengths of Hose Assemblies

For hose assemblies with straight to straight fittings, 38° seat, DIN, BNAE and flange, measure between the faces of the inserts (including flange retainer insert) as shown in example 1.
For hose assemblies with 45° or 90° Elbow fittings, 38° seat, DIN, BNAE and flange measure from the center of the elbow, as shown in example 2.
For hose assemblies with flareless fittings, DualSeal,** the measurement is from the center of the gage point to the other gage point, as shown in example 3.

How to Specify a Hose Assembly

1. Straight-to-Straight and Straight-to-Elbow Configurations

Explanation: Titeflex “130 Series” hose assembly with a straight 38° seat SS fitting at one end and an elbow 90° 38° seat SS fitting at the other end. Hose size is -08 (Nominal inside diameter in 16th inches). Hose assembly length (L) is 12.5 inches (012= length in even inches, 4 = length in fractional 1/8 inches. Assembly is equipped with a PTFE chafe sleeve.

2. Double Elbow Configuration

When ordering double elbow hose assemblies, hose size is indicated by a letter instead of number (see table below) and the dash is relocated (or deleted if a special feature code letter is added). Angular orientation between the elbows is expressed in three digits. The angle is measured in degrees counterclockwise from the centerline of the nearest fitting to the centerline of the other fitting as shown in the figure. If the desired orientation is 0 degrees, specify as 000.

Explanation: Titeflex “130 Series” hose assembly with 45° elbow 38° seat fitting SS at one end and a 90° elbow 38° seat fitting SS at the other end. Hose size is -12 (Nominal inside diameter in 16th inches). Hose assembly length (L) is 25 3/4 inches (025= length in even inches, 6 = length in fractional 1/8 inches. Orientation between the elbows is 180°. The same assembly with a PTFE chafe sleeve would be specified by dropping the dash and inserting the special feature code letter “C”. The number would be then read as 130102G0256C180.

Ordering Fittings Separately?

Individual part numbers are listed for all standard fittings included in this catalog. In general, fittings are specified by a prefix “Y”, followed by a three-digit base number and a two digit number which indicates size. A dash followed by one or two digit number designates material (stainless or lightweight construction).

Ordering Hose in Bulk?

Hose is specified by a prefix “R” followed by a three-digit number indicating type of hose. A dash followed by one or two digit number denotes size (nominal inside diameter in 16th inches). Total length of hose is specified by a second dash followed by the hose length in feet.

Pressure Test

Titeflex Aerospace hoses for airborne equipment are proof pressure tested at twice the recommended operating pressure (see hose charts for each type of assembly) before shipment. Unless otherwise specified, the test fluid used is water. Nitrogen or other pneumatic type proof pressure test can be used when specified.

R&D/Design

Titeflex Aerospace offers extensive design capabilities, specializing in PTFE Flexible Hose, Annular Convoluted Metal Hose, Rigid Tube Fabrication, and Flex-Rigid Assemblies. Titeflex Aerospace Engineers utilize the latest tools and technology, included Catia V5, and can meet all of your fluid transfer design needs. At Titeflex Aerospace, a dedicated team of R&D engineers exists to provide our customers with solutions for complex product design from concept to qualification.

Methods & Processes

Titeflex Aerospace has highly developed manufacturing processes based on a wide range of engineering experience. This results in very low reject rates and increased production efficiency. Our engineers and designers work very closely with the manufacturing team to continuously improve these methods and also maximize product reliability and durability.

Laser & Electroetch Marking

Titeflex Aerospace identifies each manufactured product using one of two permanent, non-polluting, and non-corroding methods. The laser marking process consists of laser engraving on a stainless steel tag fixed to the flexible hose assembly. The advantage of this process is the provision of permanent durable identification. When laser marking is not possible, Titeflex can provide permanent marking through electro chemical reaction (Electroetch). This is a safe, acid free, and non toxic identification process which is perfectly compatible with stainless steel tags.

Datamatrix Identification

Titeflex is equipped with specific software to translate any identification into a datamatrix or barcode system. This software is coupled with Laser and Electroetch marking devices. A dedicated reader device is used to validate and ensure workable marking for the customers.
