Low-Density Polyethylene LDPE and Linear Low-Density Polyethylene LLDPE tubing are used in a broad array of applications including cable jacketing, chemical conveyance, pneumatic and air lines, beverage/ food processing, and potable water systems.
LDPE or LLDPE?
Both have excellent flex life, but our LLDPE tubing is recommended whenever exceptional environmental stress-cracking resistance ESCR is required and for applications where push-on fittings are used. Also, LLDPE has a slightly higher pressure rating than LDPE, but LDPE is slightly more flexible. View the chemical resistance of LDPE and LLDPE.
13 Colors in Stock and Custom Sizes
Color coding is commonly used to identify various chemical or air lines within a facility or process. However, most manufacturers offer less than 6 colors, limiting the user’s choices. In our constant effort to differentiate ourselves from the competition, we offer thirteen colors.
In addition, if you have a custom color we can probably run it.
