Parker continues to refine and improve its product offerings to better serve customers, and the latest update to Parker Polyurethane Tubing is a great example. The recent nomenclature change for the 95U Series Polyurethane Tubing is designed to simplify product identification, improve consistency, and make ordering easier across the board.
If you currently specify, stock, or use Parker Polyurethane Tubing, understanding these updates will help ensure a smooth transition.
What Is Changing with Parker Polyurethane Tubing Nomenclature?
As part of a broader thermoplastic tubing update initiative, Parker has introduced a nomenclature change for its 95U Series Polyurethane Tubing. The goal is not to change the product itself, but to improve how it is identified, packaged, and referenced. This change is being implemented as a running update beginning April 15, 2026.
Key Nomenclature Updates
The updated naming structure for Parker Polyurethane Tubing includes several important enhancements:
- Product series identification included in part numbers and descriptions
- Metric tubing renamed from 95UM to 95U
- Consistent 3-digit color coding (including NAT for natural)
- Package quantity embedded directly into the part number
These changes make it easier to quickly identify tubing size, color, and packaging configuration directly from the part number.
Packaging Standardization
Another important update to Parker Polyurethane Tubing is the standardization of packaging.
- Standard packaging options:
- 100 ft retail packages
- 500 ft reels
- Select sizes may offer:
- 1000 ft reels (upon request)
What This Means for Existing Part Numbers
| Original Part Number | New Part Number |
|---|---|
| 95U-2-031-0100 | 95U-2-031-NAT-0100 |
| 95UM-4X.75-0100 | 95U-4×0.75-NAT-0100 |
Key differences
- Addition of color code (e.g., NAT, BLK, BLU)
- Inclusion of package length (e.g., 0100, 0500)
- Standardized format across imperial and metric tubing
Metric tubing now aligns with the same naming convention as imperial sizes, eliminating the separate “95UM” designation.
Parker Polyurethane Tubing 95U Series Overview
While the nomenclature is changing, the core performance and features of Parker Polyurethane Tubing remain the same.
According to the Parker CAT4660 catalog (pages B-37 and B-38), the 95U Series offers:
Key Features
- UV-resistant 95 Shore A durometer polyether-based resin
- Excellent flexibility with rubber-like elongation and recovery
- Chemical resistance typical of thermoplastics
- Kink resistance for easier routing and installation
These characteristics make Parker Polyurethane Tubing ideal for applications requiring flexibility, durability, and reliable performance.
Operating Conditions
- Temperature range: -40°F to 180°F (-40°C to 82°C)
- Working pressure ratings based on 73°F (23°C)
- Pressure decreases at elevated temperatures (refer to pressure vs. temperature charts)
