Transparent Tygon Hose
3/32" Tygon Small Oil Injection Hose - 10ft Length
Pro Marine Item 255 is transparent 3/32" Tygon hose supplied in a 10-foot length. This small-diameter flexible tubing is commonly used for PWC oil-injection line applications where 3/32" inside-diameter hose is required.
The transparent construction makes it easier to visually inspect the line and see fluid within the hose, which is particularly useful when servicing small oil-injection systems.
Need another size? Pro Marine stocks a range of Tygon hose from 3/32" through 5/16", including fuel-hose and bleed-hose options. See the complete size chart below.
Inside Diameter: 3/32"
Length: 10 Feet
Material: Tygon
Color: Transparent
Primary Application: PWC Small Oil Injection Line
Item Number: 255
What This Tygon Hose is Used For
Item 255 is intended for small-diameter fluid-line applications requiring 3/32" Tygon tubing. Pro Marine lists this hose primarily for PWC small oil-injection line applications.
Small oil-injection hoses can become hard, brittle, cracked or damaged with age. Replacing deteriorated tubing is an important part of servicing an oil-injected PWC or other compatible system.
Always verify the required inside diameter and application before replacing an existing hose.
Why Use Transparent Tygon Hose?
Transparent tubing provides an important advantage on small fluid lines: it allows the technician to visually inspect what is happening inside the hose.
Depending on the system, this can make it easier to check for fluid in the line and identify obvious air pockets or contamination during service.
Pro Marine stocks multiple transparent Tygon hose sizes for PWC, outboard, fuel-line, oil-injection and bleed-hose applications.
Use the size chart below to compare the available options and go directly to the correct product page.

View Oetiker Clamp PackChoosing the Correct Tygon Hose Size
Hose size should be matched to the fitting and system being serviced. Do not substitute a larger or smaller hose simply because it appears close in size.
For an existing oil-injection, fuel or bleed-line system, compare the original hose size and application before replacement. If the application is uncertain, verify the engine or PWC model and the required hose size before installation.
