Who is Colder Products Company?

Colder Products, a Dover company, has manufactured quick disconnect couplings and pipe fittings since 1979. Colder couplings were originally custom designed but later found to work well with a range of plumbing applications, from medical equipment to food processing. Colder’s innovative couplings and pipe fittings allow you to connect and disconnect flexible tubing quickly and safely.

Colder Couplings Uses:

• Medical: surgical, dialysis, blood pressure
• Industrial: ink printing, biohazard detection, portable water systems, engines
• Chemical: pharmaceutical manufacturing, soap dispensing

What to consider when looking for the right Colder coupling:

• The flow your application requires
• The inner and outer diameter size of your tubing
• Your application’s temperature range
• Your application’s maximum pressure
• The type and size of the coupling or the type of valve
• How the coupling will be mounted
