# 20705901 Hose Clamp | Genuine Volvo Penta Part

## 🔧 Product Description

A genuine heavy-duty approximately 4-inch T-bolt clamp used on compatible Volvo Penta large-diameter charge-air, exhaust or cooling hose connections. The T-bolt design provides high and even clamping force around the hose.

## 🚤 Compatibility

-   **Engine Family:** D, TAD

Full model list at the end of this description.

## ⚙️ Key Features

-   Approximately 4-inch clamp size
-   T-bolt and nut design provides higher retention than a light worm-drive clamp
-   Wide band distributes load around large charge-air or exhaust hose connections
-   Suitable for high-vibration and elevated-temperature engine service
-   Must be tightened to the applicable clamp specification without cutting the hose
-   Confirm hose outside diameter and connection type before ordering
-   2 used per assembly

## 🔌 Function

Applies uniform clamping force around a large-bore hose connection to prevent movement and leakage.

## ⚠️ Common Signs of Failure

-   The band or T-bolt is cracked, stretched or corroded
-   The hose leaks or moves despite correct tightening
-   The nut seizes or threads are damaged
-   The band cuts into or distorts the hose
-   Replacement is required after over-tightening or repeated removal

## 🛠️ Service Notes

-   Match the clamp to the hose outside diameter so the band closes well within its working range rather than at the very end of its travel
-   Position it over the spigot behind the bead or barb, with the screw where a driver or spanner can still reach it once everything is refitted
-   Tighten to seal, not to crush — an over-tightened worm-drive clamp cuts into soft hose and starts the leak you were trying to stop
-   Renew clamps when a hose is changed rather than reusing them, and keep band, housing and screw all marine-grade stainless so the clamp does not corrode against itself
-   Where two clamps are fitted to one connection, stagger the screw heads and recheck both after the first running period
