Aluminium Chrome Inline Non-Return Check Valve — NBR Rubber Seal

Keep your fuel, water, oil, or air lines flowing in one direction only with this professional-grade aluminium non-return check valve. Built from durable aluminium alloy with an NBR rubber seal and a polished chrome finish, this normally-closed inline check valve delivers consistent, reliable performance across a wide range of low-pressure fluid and gas applications — from marine engines and automotive carburettors to RVs, caravans, agriculture equipment, and water pump systems.

Made in Mainland China.

Key Features

  • Clear Flow-Direction Arrow: An arrow marked on the valve body indicates the correct fluid flow direction, preventing backflow and keeping fuel or fluid locked in the line — eliminating hard or slow starts caused by fuel drain-back.
  • Durable Aluminium Construction: The aluminium alloy body significantly outlasts plastic alternatives, providing long-term durability and structural integrity in demanding environments.
  • NBR Rubber Seal: The nitrile butadiene rubber (NBR) sealing element offers excellent resistance to petroleum-based fluids, oils, and gases, ensuring a tight, leak-free seal over extended use.
  • Wide Fluid Compatibility: Suitable for use with petrol, diesel, vegetable oil, paraffin, water, gas, and air — ideal for carburettors and low-pressure fuel systems.
  • Professional-Grade Versatility: Designed for marine, automotive, caravan, RV, and agricultural applications, as well as water pressure pumps and galley pumps that are not self-priming.
  • Easy Installation: Simple inline installation and replacement — no tools required beyond basic fitting; no electrical connection needed.

Frequently Asked Questions

Q: What sizes does this aluminium non-return check valve come in?

A: This inline check valve is available in four sizes: 6 mm, 8 mm, 10 mm, and 12 mm (approximately 0.24", 0.31", 0.39", and 0.47" respectively). Select the size that matches your existing hose or fuel line inner diameter for a secure, leak-free fit.

Q: What fluids and media is this check valve compatible with?

A: The valve is compatible with petrol, diesel, vegetable oil, paraffin, water, gas, and air. The NBR rubber seal provides strong resistance to petroleum-based fluids, making it well-suited for automotive carburettors, low-pressure fuel systems, marine applications, and agricultural equipment.

Q: Does this check valve require any electrical connection or special tools to install?

A: No — this is a fully mechanical, electricity-free device. It operates hydraulically via internal pressure and simply installs inline within your existing hose or pipe. No wiring, no actuator, and no special tools are required beyond basic fitting.

Q: How do I know which direction to install the valve?

A: An arrow is clearly marked on the valve body indicating the correct direction of fluid flow. Simply align the arrow with the intended flow direction when connecting it to your line, and the valve will automatically prevent any backflow.
