Quick Coupling RECTUS model 35299, internal female thread 1/4"

RECTUS quick coupling model 35299 with internal female thread 1/4" is a compact coupling designed for fast, repeatable connection and disconnection of pneumatic or fluid lines. The coupling provides a fixed female threaded interface for hoses and fittings, allowing installers to specify BSP or NPT compatibility as required. Its compact form factor makes it suitable for installation in confined spaces on tools, machines, and piping systems where reliable sealing and ease of use are important.

Advantages

This quick coupling offers a secure threaded connection with straightforward push-pull operation for the mating part, enabling rapid line changes and reduced downtime. The design focuses on reliable sealing under standard workshop and industrial pressures and minimizes air or fluid loss during coupling and uncoupling. Its threaded interface ensures a stable mechanical fit, and the compact size simplifies mounting in tight assemblies.

Suitable for

• Workshop air lines and pneumatic tool hookups
• Industrial machinery where frequent hose changes are required
• Maintenance tasks that require rapid connection and disconnection of fluid or air lines
• Assembly fixtures and test rigs with 1/4" threaded ports

Key specifications

• Connection type: internal female thread, 1/4"
• Application: pneumatic and compatible fluid lines
• Form factor: compact coupling body suitable for confined spaces
• Operation: quick connect/disconnect for mating coupling halves
• Compatibility: intended for 1/4" threaded fittings (BSP or NPT as installed)

How to use

Install the coupling by threading the internal female 1/4" port onto the corresponding external male fitting, ensuring the correct thread standard (BSP or NPT) has been selected. Tighten to the recommended torque for the installation to secure a leak-free connection. To connect, insert the matching male quick coupling half until it latches; to disconnect, release the latch according to the mating part's operation. Follow standard safety procedures for depressurizing lines before disconnecting to avoid fluid or air release.

Usage recommendations

Use compatible thread standards and appropriate sealing materials (such as PTFE tape or thread sealant) where required, and verify system pressure compatibility before use. Regularly inspect the coupling and mating parts for wear, debris, or damage, and replace components that show signs of leakage or degraded sealing performance.
