This 30 degree bend is one of the most popular fittings that we stock, it can be used in a variety of situations in an underground drainage system.Both ends of this bend are socketed to accept a length of pipe. If this pipe has been cut to length it should be chamfered and lubricated with ourandnbsp;SG100 lubricant prior to insertion into the socket to ensure the best possible seal. Double socket bends can also be used in conjunction with other fittings that have a pre-chamfered end, such as single socket bends or gullies. If you are unsure of the exact bend that you might need, we would recommend an adjustable bend. The clever design of this fitting allows it to be rotated to any angle between 0 and 90 degree. Having one of these fittings on site can save a huge amount of time if the angles on your installation donand#039;t quite line up!Please watch our overview video below
