حلقة مطاطية مانعة للتسرب

This rubber washer is a flexible 1/2 inch gasket designed to seal connections between pipes or fittings in plumbing. It creates a watertight seal, helps prevent leaks, and can absorb minor movement or vibration.

Material: rubber. Size: 1/2 inch nominal bore. Features: flexible, UV-resistant, temperature-variation tolerant, easy to install, provides an effective watertight seal and resistance to warping or misalignment.

Steps: 1) Shut off water and clean the mating surfaces. 2) Place the washer between the pipe joints or fittings. 3) Assemble the connection and hand-tighten, then snug the fitting—avoid over-tightening which can crush the washer.

Ideal for plumbing work: sealing pipe-to-pipe joints, taps, hose connectors, irrigation lines, and other 1/2 inch fittings where a watertight seal is needed.

Yes. Rubber washers are elastic and can adapt to slight misalignments or irregular shapes, helping to maintain a watertight seal.

Yes. The rubber material provides vibration damping in connected fittings, reducing movement-induced leaks.

Inspect for cracking or wear and replace if the washer shows damage. Keep connections clean and dry when not in use and replace in sets to maintain seal integrity.

This washer is made of rubber for standard plumbing use. It is not a food-contact material. Ensure compatibility with your system (e.g., potable water requirements) and avoid exposing it to chemicals that could degrade rubber.

Smaller 1/4 inch washers seal small-diameter joints, while larger 3/4 inch washers seal larger connections. Use 1/2 inch for typical mid-size pipe joints.

Optional accessories include plumber’s tape (Teflon tape) for thread sealing and compatible fittings or nuts to ensure a secure joint. Keeping a small supply of washers on hand helps with quick repairs.

Potential issues include overtightening, which can crack the washer, misalignment causing leaks, or using incompatible materials. Ensure surfaces are clean, properly aligned, and use the correct size for the joint.
