420 Glue | McMaster-Carr

Create secure bonds between parts that are already installed. Our thinnest adhesives use capillary action to pull themselves deep into close-fitting seams—like water up the roots of a tree.

Apply an accelerator first to reach a full-strength bond faster.

Thin Liquid—Seep into narrow gaps and joints that thick-liquid adhesives can't reach. Use when bonding close-fitting parts.

Thread Sealants with PTFE

Tube

PTFE provides a slippery surface that keeps threads from binding. These sealants are anaerobic, so they don’t begin to harden until coated surfaces are threaded together, blocking exposure to air.

Low Locking Strength—Sealants with low locking strength prevent threads from loosening due to vibration and can be adjusted without tools.
