Mechanically Attached Fitting ... the weldless, threadless way to join pipe/tube
Head Office: 1-877-643-8823


PYPLOK is a 360° radial swage mechanically attached fitting which permanently connects pipes for a leak free, cold connection. The system is fast, reliable and tamper proof, ideal for use in new build and maintenance works in the marine industry, where fire hazards exist and a clean piping connection is required.

DMO085 The PYPLOK connector is a metal sleeve which slides over the pipe, such as the pressfitting system. The outer diameter at each end of the connector is then swaged against the pipe in seconds using a hand held portable tool. PYPLOK fittings incorporates a sealing capability by using four non-metallic O-Rings.

PLOK DMZO 10-BTC 76-A105 F193 PYPLOK has been mechanically and environmentally tested according to many standards and procedures over the years. PYPLOK has passed combined impulse and vibration tests as well as shock and fire tests. PYPLOK was analyzed using FEA (Finite Element Analysis) to ensure compliance under ASME B31.1 / B31.3.

PYPLOK fittings can be used in a wide variety of low to high pressure piping applications in industries such as Marine & Offshore, Navy, Oil & Gas, Petrochemical, Steel, Mining and many other industrial uses. PYPLOK approvals: ABS, LR, DNV, BV, CCS, RMRS, CRN, TSSA, NAVSEA, CLASSNK, API 6FB and ISO 19921.
