Loc-Line 61505 Flex Hose Connectors 3/4 NPT Pack of 4

SKU CH-T1V8-7XJKP MPN 61505

Pack of four ¾ NPT male-threaded connectors rated to 40 psi for flexible hose assemblies

  • TypeDrain Components
  • Loc-Line 61505 connectors handle up to 40 psi
  • Pack of four speeds up multi-point installations
  • 3/4 NPT male thread fits standard plumbing fittings
  • Resists acetone, alcohol, oils and common solvents
  • Non-threaded 3/4 in end allows flexible hose attachment

What you get

The Loc-Line 61505 pack contains four flexible hose connectors built for drainage and trap assemblies. Each unit has a 3/4 inch NPT male thread on one end and a non-threaded 3/4 inch diameter on the other. The connectors are rated for a maximum pressure of 40 psi.

The spec that decides fit

The connection end uses a 3/4 inch NPT male thread, so the mating port must match that exact thread type and size. The opposite end is a plain 3/4 inch non-threaded opening for push-fit or clamp attachment. Maximum working pressure is 40 psi.

Install notes

Thread the NPT end into the female port using appropriate sealant for a leak-free joint. The plain end accepts a hose or tube secured with a clamp. The material resists acetone, alcohol, detergents, fuels, oils and sodium hydroxide. Over-tightening the thread or exceeding the pressure rating are the common failure points.

Questions about this item

What does the 40 psi pressure rating mean when the connector is installed in a plumbing system?

The 40 psi rating is the maximum internal pressure the Loc-Line 61505 connector can safely withstand during operation. Exceeding this limit risks leaks or fitting failure, so system pressure must stay at or below this value.

How does the 3/4 NPT thread standard affect compatibility with existing pipework?

The male 3/4 inch NPT end follows the US National Pipe Taper standard, creating a seal through thread interference. It mates with any female 3/4 NPT fitting, but requires thread sealant or tape for a leak-free joint.

What clearance and alignment are needed to mount the four connectors in a tight assembly?

Each connector has a 3/4 inch non-threaded diameter on the hose end and a male 3/4 NPT thread on the other. Allow enough space for the NPT engagement length plus hose bend radius to avoid stress on the joints.
