Uniseals and grommet/barb fittings
are an economical fast installation choice for plumbing connection to another pipe or vessel such as drums and barrels, sumps, filters, aquariums, etc.
Uniseals for flat or curved surfaces - work in areas where traditional bulkhead fittings will not such as curved surfaces, i.e. pipe wall or round drum wall. Also can be used when access to inside of tank is not practical for tightening bulkhead nuts. Uniseals are just pressed into a drilled hole.
Applications are varied including Plumbing, Aquaculture, Hydroponics, Aquaponics, Agriculture, Marine/Boating, Chemical and Building Industries.
Uniseals are manufactured from a chemical resistant rubber-like thermoplastic. Good resistance to water and oil based materials with good UV exposure resistance. Chemical resistance chart available on request.
Simply drill appropriate sized hole*, insert Uniseal and push pipe through Uniseal from large diameter side of Uniseal. Use a soapy solution or silicone
o-ring lube to help insert pipe. Makes a tight waterproof seal. Inserted pipe must be free from sharp edges or points to avoid cutting into Uniseal. Pipe/tank wall thicknesses should be from 1/8” to 1/2”
on larger Uniseals. See Bulkhead fitting page for accessories such as Intake Screens and elbow and
straight slip barbs which will fit all standard PVC socket fittings. We also have various valves that can be used to regulate flow to or from tanks / pipes where Uniseal is fitted to.
