What it is
The Ideal 177639 is an SRV clip supplied for Ideal heat interface units (HIUs). It holds the safety relief valve (SRV) securely in its housing so the valve stays correctly seated during operation and service work. The clip is produced under Caradon manufacture and supplied under the Ideal brand for Ideal Commercial appliances.

- Water weeping or discharging from the relief valve outlet where the valve body is not seating squarely.
- Movement or vibration of the valve assembly within the heat interface unit.
