Product Details

The Mishimoto MMDCC-40SBK is a 40mm straight silicone coupler designed for use in performance cooling, intercooler, and boost piping systems. Engineered from high-grade reinforced silicone, this straight coupler provides a durable, flexible, and leak-free connection between same-diameter pipes and tubes.

Key Features:

  • 40mm (approximately 1.57") inner diameter straight coupler for same-size pipe connections
  • Constructed from premium multi-ply reinforced silicone for superior heat and pressure resistance
  • Black finish for a clean, stealthy under-hood appearance
  • Resistant to cracking, tearing, and degradation from engine heat and fluids
  • Flexible design accommodates minor misalignment between pipes
  • Compatible with standard intercooler, intake, and cooling system plumbing
  • Suitable for both OEM replacement and custom fabrication applications

Mishimoto silicone couplers are a popular upgrade over factory rubber hoses, offering improved durability and a longer service life under high-temperature and high-pressure conditions. The MMDCC-40SBK is ideal for enthusiasts building or upgrading turbo, intercooler, or radiator piping systems.

Easy shopping and easy ordering

Very good service

I never received anything about shipping so I contacted customer support. They said it was a direct shipment and they would check on it for me and get back to me. I never heard back from them. Shortly after that I did receive a message from the carrier saying they have my shipment and scheduled a delivery. They said they would call me 30 mins before the delivery so I could get off work and come to inspect it before signing for it. That didnt' happen either my wife called me first thing in the morning and say they are here delivering it now so I had to run home so I could inspect it. The driver was really nice and waited for me to get there.

I was pretty happy with the service. I ordered the part on a Sunday afternoon and paid $9.99 for 2 day delivery and it arrived on Friday 5 days later so not sure I got what I paid for in that regard.

Excellent price and speedy delivery.

Very quick and cheap
