This Viva 1 1/4 inch SWIVEL 'P' TRAP from FixTheBog is made from high-quality polypropylene and features a 75mm water seal. It is suitable for 1 1/4 inch pipes and has a universal outlet compatible with plastic, copper, and lead pipes. The trap utilizes easy-grip compression nuts, a tapered rubber seal, a rubber 'O' ring, and a slip ring for a secure, watertight seal.
