Truflo® Lotorq LT Series Low Torque ANSI Flange Gaskets

Truflo® Lotorq LT Series Low Torque ANSI Flange Gaskets

Full Faced ANSI Flange Gaskets-150lb

Excellent for Non Metallic Piping System


Lotorq LT Series Low Torque Gaskets are recommended for all types of non-metal piping systems to prevent Initial Flange Breakage due to Bolt over-tightening. The unique Raised Double Convex Ring Design provides Excellent Sealing with Less than Half Bolt Torque Required for flat face gaskets. The PTFE gaskets have PTFE sheet material bonded directly to EPDM… Your seal in now Energized with Increased Elasticity…


  • Low Flange Bolt Torques Required for Positive Seal – Due to the molded raised face – patented double convex ring design

  • Ideal for Thermoplastic Piping Systems, also metal or plastic lined metal pipe systems for up to 250 psi

  • Excellent Chemical Resistance – PTFE-bonded gaskets are suitable for extremely aggressive chemical services.

  • Longer Gasket Life – Because lower flange pressures are required for sealing. PTFE is energized forming an excellent seal.

  • Low Torque – Raised or Ring Design

  • Designed to provide positive seal

  • No over – Tightening Required


All flange gaskets 1/2? to 12” are to be LoTorq LT Series molded raised face type with full face ANSI B16.1 (Class 150) dimensions. Material will be pure EPDM (or PTFE (Teflon)-bonded EPDM).

A tab will identify Gasket Material. Raised Convex Molded Rings will provide effective sealing using low bolt torques.


PTFE = PTFE (Teflon bonded EPDM)
