Estimated Weight Reference
Parameter
Details
Estimated reference weight
907 g, excluding packaging
Tubing calculation
75.60 g/m × 12.0 m = 907.200 g; based on same-size ester-based US98A tubing
This is a reference estimate, not a published AirTAC mass or a measured weight of the supplied product. The coupling benchmark estimates mass only and does not establish dimensional or functional interchangeability.
Features and Operation
Thermoplastic polyurethane material is described in the catalog as meeting RoHS environmental requirements.
High elasticity and a small bending radius help route the tubing through confined spaces.
The catalog describes improved kink resistance compared with other plastic tubing.
Good flexibility supports repeated extension and contraction.
Abrasion resistance supports use where the tubing is exposed to wear.
Low gas permeability helps reduce leakage and contamination.
Resistance to dissolution and low compression help maintain the material’s physical properties.
The Chinese catalog identifies air and water as applicable media.
Avoid acidic or alkaline environments, chemical agents, organic solvents, seawater, corrosive gases, and prolonged exposure to sunlight or heat. The catalog warns that these conditions can cause cracking or damage.

Pressure and Hardness Reference Charts
The pressure-retention chart plots temperature at 23, 37, 51 and 65°C against 0–100% of reference working pressure. Curves compare nylon, PU, PE and PVC; use the PU curve for this material. It is a graphical comparison and does not replace the size-specific pressure table.
The adjacent hardness comparison uses Shore A, Shore D and Rockwell R scales. Visible ranges are approximately Shore A 20–100, Shore D 40–90 and Rockwell R 50–150. This comparison chart does not assign a numerical hardness to the UCS model.
The catalog includes a nominal 3:1 pressure safety-factor note. The lower-pressure table lists 0.8 MPa working and 2.0 MPa burst pressure; these values are reproduced as printed rather than recalculated.

Lower-pressure color note
The catalog also mentions gray in the nine-color lower-pressure note, but does not assign its ordering-code token in the UCS color table.
Matching Accessory Codes and Conditions
This UCS order has coupling form 1 and is supplied without couplings. The listed male and female GX parts are optional, separately ordered tube-end choices; select only the type and quantity required by the verified assembly. They do not change the ordered supply configuration or include any host equipment. Straight-end code A retains the original 30 cm / 10 cm arrangement; it is independent of coupling form 1, 2 or 3. Do not treat the list as a mandatory male/female pair or as approval for arbitrary external mating components.
The UCS tube is rated 1 MPa working pressure at 23°C, with 3 MPa burst pressure that is not an operating rating. Apply the PU temperature-derating curve within the tube’s −20–70°C range and every stricter system limit. The 12 × 8 mm tube has a 60 mm catalogue bending radius. Support the coiled tube and its ends against twisting, pull and kinking; the published working-state length of 0.8–0.9 times material length is not a guarantee of permissible installation tension or an overall assembly dimension.
The pipe-end table does not publish separate GX body dimensions, thread specifications, materials, pressure, temperature or fluid ratings. Confirm these and the required tube-end retention, sealing and assembly method with the supplier before use; the tube’s air/water statement and pressure rating do not establish the rating of the coupling or finished assembly. Verify compatibility with the actual fluid, lubricant, contaminants and environment; retain the tube restrictions on acids, alkalis, solvents, seawater, corrosive gases, prolonged sunlight and excessive heat. Isolate and verify zero pressure before assembling, removing or servicing the connection. No vacuum, zero-leak isolation, cross-series interchangeability, current-stock or retail-pack quantity is established here.

Optional male tube-end quick coupling
Catalog-listed male GX quick coupling for the UCS 12 mm OD × 8 mm ID tube end. Both tube dimensions must match; the male designation describes the quick-coupling end, not a published pipe-thread standard. This is a separately selected tube-end option, not an included part or a verified external-equipment interface.GX-400-40PP
Optional female tube-end quick coupling
Catalog-listed female GX quick coupling for the UCS 12 mm OD × 8 mm ID tube end. Both tube dimensions must match; the female designation describes the quick-coupling end, not a published pipe-thread standard. This is a separately selected tube-end option, not an included part or a verified external-equipment interface.GX-230-40SP
