4″ URT (Urban Round Thread) Lugged Female × 3″ BSPP Male Adaptor – Natural Polypropylene – CPP®

CPP® adaptor connecting a 4″ URT lugged female connection to a 3″ BSPP male connection, moulded in straight natural polypropylene.

URT means Urban Round Thread. It is a coarse round-thread connection used in the UK and based on traditional fire-hose suction coupling patterns. Similar round-thread systems have been used by different manufacturers, so nominal size alone does not always guarantee interchangeability.

Compatibility: Check the mating thread form and dimensions before ordering. This is particularly important when matching older suction couplings and 4″ round-thread fittings, where compatibility can vary between manufacturers.

Pressure rating — water service

This rating applies to the CPP® straight natural polypropylene Lugged coupling range and is based on water service. The complete assembly is limited by its lowest-rated component. Verify suitability for the intended liquid, temperature and operating conditions before use.

Before use, confirm both thread forms and sizes match the mating connections.
