Subject: Coolant hose appearance

Dear Valued Customer,

Purosil is making changes that will affect the appearance, but not performance, of our coolant hoses. These changes will be phased in over the next few months. Therefore during the transition, you could receive hoses on the same order that look different. Each change is discussed below.

Coolant hose liners:
Purosil’s coolant hose liners are different shades of red, ranging from a cherry red to a ‘brick’ red. We are consolidating the colors to a brick red, the same color as the heater hose liner. This change will affect all coolant hose including straight (such as 70 and 7030 series), elbows (such as 90 and 9046 series) and hump and step (such as 77 and 7641 series).

Multi-ply Formed hoses: (Elbows)
Purosil manufactures silicone hose with either a matte or a glossy finish. We are transitioning the matte finish hoses to a glossy finish. The appearance of the cover is a result of the tape the hose is wrapped with. It is to hold its’ shape during the cure cycle and is removed afterward. The hose construction remains unchanged.
